Jorropo e30ce3c498 sync/atomic: make intrinsics noescape except 64bits op on 32bits arch and unsafe.Pointer
Fixes #16241

I made 64 bits op on 32 bits arches still leak since it was kinda promised.

The promised leaks were wider than this but I don't belive it's effect can
be observed in an breaking maner without using unsafe the way it's currently
setup.
