As suggested by Bryan in CL 249759, remove the forwarding aliases in
cmd/cover and use the symbols from golang.org/x/tools directly.
cmd/cover is not an importable package, so it is fine to remove these
exported symbols.

After CL 179377, this change deletes all the prior cmd/cover code
and instead vendors and type aliases code using the significantly
optimized golang.org/x/tools/cover, which sped up ParseProfiles by
manually parsing profiles instead of a regex. The speed up was:
name old time/op new time/op delta
ParseLine-12 2.43µs ± 2% 0.05µs ± 8% -97.98% (p=0.000 n=10+9)
name old speed new speed delta
ParseLine-12 42.5MB/s ± 2% 2103.2MB/s ± 7% +4853.14% (p=0.000 n=10+9)
Fixes #32211.

Introduces a wrapper around os/exec, internal/execabs, for use in
all commands. This wrapper prevents exec.LookPath and exec.Command from
running executables in the current directory.
All imports of os/exec in non-test files in cmd/ are replaced with
imports of internal/execabs.
This issue was reported by RyotaK.

As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)
Update the Go tree to use the preferred names.
As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.
ReadDir changes are in a separate CL, because they are not a
simple search and replace.

A recent change added a title to the HTML coverage report but
neglected to include the package name. Add the package name here.
It's a little trickier than you'd think because there may be multiple
packages and we don't want to parse the files, so we just extract
a directory name from the path of the first file. This will almost
always be right, and has the advantage that it gives a better result
for package main. There are rare cases it will get wrong, but that
will be no hardship.
If this turns out not to be good enough, we can refine it.

Function declarations with blank ("_") names do not introduce a binding,
and therefore cannot be referenced or executed (in fact, they do not
make it into the final compiled binary at all). As such, counters
defined while annotating their bodies will always be zero.
These types of functions are commonly used to create compile-time
checks (e.g., stringer) which are not expected to be executed.
Skip over these functions when annotating a file, preventing the unused
counters from being generated and appearing as uncovered lines in
coverage reports.

On Windows, os.Chmod and syscall.Chmod toggle the FILE_ATTRIBUTES_
READONLY flag depending on the permission bits. That's a bit odd but I
guess some compromises were made at some point and this is what was
chosen to map to a Unix concept that Windows doesn't really have in the
same way. That's fine. However, the logic used in Chmod was forgotten
from os.Open and syscall.Open, which then manifested itself in various
places, most recently, go modules' read-only behavior.
This makes syscall.Open consistent with syscall.Chmod and adds a test
for the permission _behavior_ using ioutil. By testing the behavior
instead of explicitly testing for the attribute bits we care about, we
make sure this doesn't regress in unforeseen ways in the future, as well
as ensuring the test works on platforms other than Windows.
In the process, we fix some tests that never worked and relied on broken
behavior, as well as tests that were disabled on Windows due to the
broken behavior and had TODO notes.

When adding coverage counters to a block, the block's statement list is
mutated. CL 77150 removed the part where the mutated list is assigned
back to its parent node; this was confusing ast.Walk, which would then
lose its place and stop walking the current block, dropping counters in
the process.
This change has addCounters make a copy of the list before mutating
it, so that the original list doesn't change under Walk's feet.

Telling whether a string is a valid Go identifier can seem like an easy
task, but it's easy to forget about the edge cases. For example, some
implementations out there forget that an empty string or keywords like
"func" aren't valid identifiers.
Add a simple implementation with proper Unicode support, and start using
it in cmd/cover and cmd/doc. Other pieces of the standard library
reimplement part of this logic, but don't use a "func(string) bool"
signature, so we're leaving them untouched for now.
Add some tests too, to ensure that we actually got these edge cases
correctly.
Since telling whether a string is a valid identifier requires knowing
that it's not a valid keyword, add IsKeyword too. The internal map was
already accessible via Lookup, but "Lookup(str) != IDENT" isn't as easy
to understand as IsKeyword(str). And, as per Josh's suggestion, we could
have IsKeyword (and probably Lookup too) use a perfect hash function
instead of a global map.
Finally, for consistency with these new functions, add IsExported. That
makes go/ast.IsExported a bit redundant, so perhaps it can be deprecated
in favor of go/token.IsExported in the future. Clarify that
token.IsExported doesn't imply token.IsIdentifier, to avoid ambiguity.
Fixes #30064.

cmd/cover has always assumed that package x/y/z can be
found in $GOPATH/src/x/y/z (roughly; by using go/build).
That won't be true for too much longer. Instead, run the
go command to find out where packages are.
This will make 'go tool cover' safe for use with Go modules
when they are in use in Go 1.11, and it continues to work
with the existing Go toolchains too.
An alternative would be to modify the cover profile format
to record file names directly, but that would require also
updating golang.org/x/tools/cover/profile and any tools
that use it, which seems not worth the trouble.
(That fork of the code does not contain any code to resolve
package names to directory locations, so it's unaffected.)
No new test here: cmd/go's TestCoverageFunc tests this code.
Fixes #25318 (when people use Go 1.11 instead of vgo).

That works on gofmt'ed code, but fails if the code looks like "}else".
When there is no space between the "{" and the "else", the new block
is inserted into a location that we are deleting, leading to the
"overlapping edits" mentioned above.

cmd/cover rewrites Go source code to add coverage annotations.
The approach to date has been to parse the code to AST, analyze it,
rewrite the AST, and print it back out. This approach fails to preserve
line numbers in the original code and has a very difficult time with
comments, because go/printer does as well.
This CL changes cmd/cover to decide what to modify based on the
AST but to apply the modifications as purely textual substitutions.
In this way, cmd/cover can be sure it never adds or removes a newline
character, nor a comment, so all line numbers and comments are
preserved.
This also allows us to emit a single //line comment at the beginning
of the translated file and have the compiler report errors with
correct line numbers in the original file.
Fixes #6329.
Fixes #15757.

Fixed an error that occurred in atomic mode. cover adds a global
variable declaration that forces sync/atomic to be used. fixDirectives
was confused by this declaration since it has an invalid
position. These declarations are now skipped.

Previously, cover printed directives (//go: comments) near the top of
the file unless they were in doc comments. However, directives
frequently apply to specific definitions, and they are not written in
doc comments to prevent godoc from printing them. Moving all
directives to the top of the file affected semantics of tests.
With this change, directives are kept together with the following
top-level declarations. Only directives that occur after all top-level
declarations are moved.

Parser doesn't attach some compiler directives to anything in the tree.
We have to explicitely retain them in the generated code. This change,
makes cover explicitely print out any compiler directive that wasn't
handled in the ast.Visitor.

Consider a switch like
switch x {
case foo:
f()
g()
}
Before, the coverage annotation for the block calling f and g included
in its position span the text for 'case foo:'. This looks nice in the coverage
report, but it breaks the invariant that coverage blocks are disjoint if
you have a more complex expression like:
switch x {
case func() int { return foo }():
f()
g()
}
Then the coverage analysis wants to annotate the func literal body,
which overlaps with the case body, because the case body is considered
to begin at the case token.
Change the annotation for a case body to start just after the colon of
the case clause, avoiding any potential conflict with complex case
expressions. Could have started at the colon instead, but it seemed
less weird to start just after it.
Fixes #16540.
