a Go compiler sharing a back end with a C/C++ compiler must take care
to disable optimizations that are invalid for Go.

Note that the prohibition on introducing data races
does not apply if the compiler can prove that the races
do not affect correct execution on the target platform.
For example, on essentially all CPUs, it is valid to rewrite
