We don't usually reformat the test directory, but all of the files in
test/typeparam are syntactically valid. I suspect the misformattings
here are because developers aren't re-installing gofmt with
-tags=typeparams, not intentionally exercising non-standard
formatting.

dictionaries
The (*T).M method expression is where M is a value method, but the type
(*T) is a pointer to the main type. In this case, after following any
embedded fields, we need to add an extra star operator when using the
receiver arg in the closure call.
Thanks to Cuong for finding/pointing out an example for this case
(typeparam/mdempsky/14.go) This example also shows that we now need the
ability to export/import OEFACE and OIDATA, which I added.

dictionaries
This is code in progress to generate the two main other types of entries
in dictionaries:
- all types in the instantiated function derived from the type
arguments (which are currently concrete, but will eventually be
gcshapes)
- pointers (i.e. mainly the unique name) to all needed sub-dictionaries
In order to generate these entries, we now generate cached information
gfInfo about generic functions/methods that can be used for creating the
instantiated dictionaries. We use the type substituter to compute the
right type args for instantiated sub-dictionaries.
If infoPrintMode is changed to true, the code prints out all the
information gathered about generic functions, and also the entries in
all the dictionaries that are instantiated. The debug mode also prints
out the locations where we need main dictionaries in non-instantiated
functions.
Other changes:
- Moved the dictionary generation back to stencil.go from reflect.go,
since we need to do extra analysis for the new dictionary entries. In
the process, made getInstantiation generate both the function
instantiation and the associated dictionary.
- Put in small change for now in reflect.go, so that we don't try
generate separate dictionaries for Value[T].get and the
auto-generated (*Value[T]).get. The auto-generated wrapper shouldn't really
need a dictionary.
- Detected, but not handling yet, a new case which needs
dictionaries - closures that have function params or captured
variables whose types are derived from type arguments.
- Added new tests in dictionaryCapture for use of method
value/expressions in generic functions and for mutually recursive
generic functions.

This CL copies go/build's splitQuoted function (used for parsing #cgo
directives within `import "C"` preambles) to parse test recipe
commands. In particular, this now allows writing "build" and "run"
tests that use -gcflags to pass multiple compiler flags.

There's no outer function in these cases, so we won't be reading
the dictionary as a subdictionary from the outer scope's dictionary.
It will always be a compile-time constant.

When converting from a generic function to a concrete implementation,
add a dictionary argument to the generic function (both an actual
argument at each callsite, and a formal argument of each
implementation).
The dictionary argument comes before all other arguments (including
any receiver).
The dictionary argument is checked for validity, but is otherwise unused.
Subsequent CLs will start using the dictionary for, e.g., converting a
value of generic type to interface{}.
Import/export required adding support for LINKSYMOFFSET, which is used
by the dictionary checking code.
