Ian Lance Taylor 7e64377903 cmd/compile: only support -race and -msan where they work
Consolidate decision about whether -race and -msan options are
supported in cmd/internal/sys. Use consolidated functions in
cmd/compile and cmd/go. Use a copy of them in cmd/dist; cmd/dist can't
import cmd/internal/sys because Go 1.4 doesn't have it.

Fixes #24315
