cmd/go,cmd/compile,sync: remove special import case in cmd/go CL 253748 introduced a special case in cmd/go to allow sync to import runtime/internal/atomic. Besides introducing unnecessary complexity into cmd/go, this breaks other packages (like gopls) that understand how imports work, but don't understand this special case. Fix this by using the more standard linkname-based approach to pull the necessary functions from runtime/internal/atomic into sync. Since these are compiler intrinsics, we also have to tell the compiler that the linknamed symbols are intrinsics to get this optimization in sync. Fixes #42196.
