reflect.callReflect and reflect.callMethod are called from special
functions makeFuncStub and methodValueCall. The runtime expects
that it can find the first argument (ctxt) at 0(SP) in
makeFuncStub and methodValueCall's frame. Normally callReflect and
callMethod already do not modify the argument, and keep it alive.
But the compiler-generated ABI wrappers don't do that. Special
case the wrappers to not clobber its arguments.

Checker.finals and the corresponding atEnd were added in CL 191418 as a
mechanism to postpone interface type comparison until after all
interfaces were complete. In the intervening CL 195837 we've adopted a
convention of ensuring that interfaces are complete before comparing
them. Since then we've also added the additional case of expansion for
lazily resolving syntax.
Checker.later defers resolution of types until points in the checking
pass where all reachable types can be fully type checked, so the concept
of finals should no longer be necessary.

Currently, if we have AX=a and BX=b, and we want to make a call
F(1, a, b), to move arguments into the desired registers it emits
MOVQ AX, CX
MOVL $1, AX // AX=1
MOVQ BX, DX
MOVQ CX, BX // BX=a
MOVQ DX, CX // CX=b
This has a few redundant moves.
This is because we process inputs in order. First, allocate 1 to
AX, which kicks out a (in AX) to CX (a free register at the
moment). Then, allocate a to BX, which kicks out b (in BX) to DX.
Finally, put b to CX.
Notice that if we start with allocating CX=b, then BX=a, AX=1,
we will not have redundant moves. This CL reduces redundant moves
by allocating them in different order: First, for inpouts that are
already in place, keep them there. Then allocate free registers.

TestScript sets the GOEXPERIMENT environment variable to the value of
buildcfg.GOEXPERIMENT() with the intent that tests can use this to
inspect the value of buildcfg.GOEXPERIMENT. This has the unfortunate
side-effect of also affecting the experiments enabled for all builds
done by TestScript. For the most part this is harmless, but
GOEXPERIMENT can be GOOS/GOARCH-sensitive, so if a test changes GOOS
or GOARCH, it will continue to use the GOEXPERIMENT from the host
GOOS/GOARCH rather than what makes sense (or is even allowed) in the
test's GOOS/GOARCH. In fact, prior to CL 307819, TestScript set
GOEXPSTRING instead of GOEXPERIMENT because it previously captured
objabi.Expstring(), so the captured value didn't affect the build.
There's only one experiment that actually uses TestScript's
GOEXPERIMENT and there's a much better way to write that test now such
that it doesn't need to read GOEXPERIMENT at all. Hence, this CL
rewrites this test and drops GOEXPERIMENT from TestScript.
This should fix the *-regabi builders.

Currently, specifying GOEXPERIMENT=regabi will turn on all regabi
sub-experiments, but GOEXPERIMENT=noregabi won't turn anything off.
Regabi also isn't a "real" experiment in the sense that nothing in the
code base should depend on it as an experiment flag (it should depend
on the appropriate sub-experiments).
Hence, drop Regabi from goexperiment.Flags and make "regabi" in
GOEXPERIMENT be a real alias for all of the sub-flags, so regabi will
turn on all of the sub-flags and noregabi will turn off all of the
sub-flags.
This way, once we enable the sub-experiments in the baseline
configuration, it will be easy to turn off with "noregabi".

Parser object resolution is an auxiliary feature in which the parser
attempts to resolve identifiers to their declarations. In functionality,
it significantly overlaps with go/types and in fact cannot be correctly
computed at parse-time without type information (for example, it is
generally not possible to resolve k in the composite lit c{k: v}). Due
to these limitations, it is of limited utility and rarely used.
Now that object resolution is isolated as a post-processing pass, it is
trivial to offer a parser mode that skips it entirely. This CL adds that
mode.

When resolving the function scope, we must be careful about the order in

Using ordering allows us to avoid passing around temporary scopes for
field declarations.
Add a bunch of tests for this behavior, and skip "_" in resolution tests

The build.Default context really needs to accurately describe

(The cleanups I made in golang.org/x/tools were long overdue
but are not strictly necessary for making regabi work; this CL is.)
Having moved the GOEXPERIMENT parsing into internal/buildcfg,
go/build can now use it to set up build.Default, in the new field
ToolTags, meant to hold toolchain-determined tags (for now,
just the experiments). And at the same time we can remove the
duplication of GOOS and GOARCH defaults.
And then once build.Default is set up accurately, the special case
code in cmd/go itself can be removed, and the special case code
in test/run.go is at least a bit less special.
