The current StdSizes most closely matches the gc compiler, and the uses I know of that care which compiler the sizes are for are all for the gc compiler, so call the existing implementation "gc".

The original analysis of the Go corpus assumed that these stripped monotonic time. During the design discussion we decided to try not stripping monotonic time here, but existing code works better if we do. See the discussion on golang.org/issue/18991 for more details. For #18991.

This is a follow-up to CL 36893. Move the unlikely branch in the wrapper prologue to the end of the function, where it has minimal impact on the instruction cache.

The test assumed that passing an unknown option to the Fortran compiler would cause the compiler to fail. Unfortunately it appears that some succeed. It's irrelevant to the actual test, which is verifying that the flag was indeed passed. Fixes #19080.

The builtin runtime package definitions intentionally diverge from the actual runtime package's, but this only works as long as they never overlap. To make it easier to expand the builtin runtime package, this CL now loads their definitions into a logically separate "go.runtime" package. By resetting the package's Prefix field to "runtime", any references to builtin definitions will still resolve against the real package runtime. Fixes #14482. Passes toolstash -cmp.
