Handlers can be registered for specific hosts by specifying the host as
part of the mux pattern. If a trailing slash route is registered for
these host-based patterns, shouldRedirect should indicate that
a redirect is required.
This change modifies shouldRedirect to also take the host of the
request, and now considers host-based patterns while determining if
a request should be redirected.

We've had a series of problems with tests unexpectedly (and innocently)
looking at system files that appear to (but don't) change in meaningful ways,
like /dev/null on OS X having a modification time set to the current time.
Cut all these off by only applying file change detection to the local package
root: the GOROOT or specific sub-GOPATH in which the package being tested
is found.
(This means that if you test reads /tmp/x and you change /tmp/x, the cached
result will still be used. Don't do that, or else use -count=1.)

Given an inlinable method M in package P:
func (r *MyStruct) M(...) {
When M is compiled within its home package, the source position that
the compiler records for 'r' (receiver parameter variable) is
accurate, whereas if M is built as part of the compilation of some
other package (body read from export data), the declaration line
assigned to 'r' will be the line number of the 'import' directive, not
the source line from M's source file.
This inconsistency can cause differences in the size of abstract
parameter DIEs (due to variable-length encoding), which can then in
turn result in bad abstract origin offsets, which in turn triggers
build failures on iOS (dsymutil crashes when it encounters an
incorrect abstract origin reference).
Work around the problem by removing the "declaration line number"
attribute within the abstract parameter abbreviation table entry. The
decl line attribute doesn't contribute a whole lot to the debugging
experience, and it gets rid of the inconsistencies that trigger the
dsymutil crashes.
Updates #23374.

Suppose you build the Go toolchain in directory A,
move the whole thing to directory B, and then use
it from B to build a new program hello.exe, and then
run hello.exe, and hello.exe crashes with a stack
trace into the standard library.
Long ago, you'd have seen hello.exe print file names
in the A directory tree, even though the files had moved
to the B directory tree. About two years ago we changed
the compiler to write down these files with the name
"$GOROOT" (that literal string) instead of A, so that the
final link from B could replace "$GOROOT" with B,
so that hello.exe's crash would show the correct source
file paths in the stack trace. (golang.org/cl/18200)
Now suppose that you do the same thing but hello.exe
doesn't crash: it prints fmt.Println(runtime.GOROOT()).
And you run hello.exe after clearing $GOROOT from the
environment.
Long ago, you'd have seen hello.exe print A instead of B.
Before this CL, you'd still see hello.exe print A instead of B.
This case is the one instance where a moved toolchain
still divulges its origin. Not anymore. After this CL, hello.exe
will print B, because the linker sets runtime/internal/sys.DefaultGoroot
with the effective GOROOT from link time.
This makes the default result of runtime.GOROOT once again
match the file names recorded in the binary, after two years
of divergence.
With that cleared up, we can reintroduce GOROOT into the
link action ID and also reenable TestExecutableGOROOT/RelocatedExe.
When $GOROOT_FINAL is set during link, it is used
in preference to $GOROOT, as always, but it was easier
to explain the behavior above without introducing that
complication.

Fixes #20284.

The linker has been applying -X options before loading symbols,
meaning that when it sees -X y=z it creates a symbol named y
and initializes its string data to z. The symbol named y is marked
"DUPOK" so that when the actual packages are loaded, no error is
emitted when the real y is seen. The predefined y's data is used
instead of whatever the real y says.
If we define -X y=z and we never load y, then the predefined symbol
is dropped during dead code elimination, but not in shared library
builds. Shared library builds must include all symbols, so we have to
be more careful about not defining symbols that wouldn't have
appeared anyway.
To be more careful, save the -X settings until after all the symbols
are loaded from the packages, and then apply the string changes
to whatever symbols are known (but ignore the ones that were not
loaded at all). This ends up being simpler anyway, since it doesn't
depend on DUPOK magic.
Makes CL 86835 safe.

The rest of the line is printed when the benchmark ends.

This just adds support on ELF systems, which is OK for now since that
is all that gccgo works on.
For the archive file generated by the compiler we add a new file
_buildid.o that has a section .go.buildid containing the build ID.
Using a new file lets us set the SHF_EXCLUDE bit in the section header,
so the linker will discard the section. It would be nicer to use
`objcopy --add-section`, but objcopy doesn't support setting the
SHF_EXCLUDE bit.
For an executable we just use an ordinary GNU build ID. Doing this
required modifying cmd/internal/buildid to look for a GNU build ID,
and use it if there is no other Go-specific note.
This CL fixes a minor bug in gccgoTOolchain.link: it was using .Target
instead of .built, so it failed for a cached file.
This CL fixes a bug reading note segments: the notes are aligned as
reported by the PT_NOTE's alignment field.

It is natural for tools to take a large string concatenation like
"1" + "1" + "1" + ... + "1"
and translate that into a sequence of go/constant calls:
x := constant.MakeString("1")
x = constant.BinaryOp(x, token.ADD, constant.MakeString("1"))
x = constant.BinaryOp(x, token.ADD, constant.MakeString("1"))
x = constant.BinaryOp(x, token.ADD, constant.MakeString("1"))
x = constant.BinaryOp(x, token.ADD, constant.MakeString("1"))
...
If the underlying representation of a string constant is a Go string,
then this leads to O(N²) memory for the concatenation of N strings,
allocating memory for "1", "11", "111", "1111", and so on.
This makes go/types and in particular cmd/vet run out of memory
(or at least use far too much) on machine-generated string concatenations,
such as those generated by go-bindata.
This CL allows code like the above to operate efficiently, by delaying
the evaluation of the actual string constant value until it is needed.
Now the representation of a string constant is either a string or an
explicit addition expression. The addition expression is turned into
a string the first time it is requested and then cached for future use.
This slows down the use of single strings, but analyses are likely not
dominated by that use anyway. It speeds up string concatenations,
especially large ones, significantly.

Fixes #23348 (originally reported as cmd/vet failures in comments on #23222).
This makes constant.Values of Kind String no longer meaningful for ==, which
required fixes in go/types. While there, also fix go/types handling of constant.Values
of Kind Int (for uint64), Float, and Complex.

I marked every test that takes more than 0.5 seconds on my machine
as something to run only when not in -short mode, or in -short mode
on the beefy linux/amd64, windows/amd64, and darwin/amd64 builders.
I also shortened a few needlessly-expensive tests where possible.
Cuts the time for go test -short cmd/go from 45s to 15s on my machine.
Should help even more on some of our builders and slower user machines.
Fixes #23287.

The docs were too specific. Make it vaguer. There are conditions for
which the Transport will try to reuse a connection anyway, even if the
Response Body isn't read to EOF or closed, but we don't need to get
into all the details in the docs.

CL 84735 strengthened the -x test to make sure commands succeed,
using set -e, but the gcc flag tests can fail. Change them to say || true.
