Support atomic write operations in stack safety
This has two benefits:
* we can now mark allocas that are used in atomic operations as safe
* this fixes a bug that would incorrectly mark all atomic writes as safe
in HWASan instrumentation. this is because stack safety keeps a list
of all *unsafe* operations that are reachable from an alloca, but it
did not analyze atomic writes, so it would always mark them as safe.
