runtime, sync/atomic: use write barrier for atomic pointer functions
This copies atomic_pointer.go from 1.10rc2. It was omitted during the
transition of the runtime from C to Go, and I forgot about it.
This may help with https://gcc.gnu.org/PR84215.

This patch restricts the set of cases in which we allow the generation of
location attributes for variables that are not defined in the current unit.
For such variables with complex DECL_VALUE_EXPR trees, generating a location
attribute can end up creating relocations to text symbols in the debug section
of LTO object files, which is not valid.
