In C++ it's UB to use undeclared values as enum. And there is support __ATOMIC_HLE_ACQUIRE and __ATOMIC_HLE_RELEASE need such values. So use `int` in TSAN interface, and mask out irrelevant bits and cast to enum ASAP. `ThreadSanitizer.cpp` already declare morder parameterd in these functions as `i32`. This may looks like a slight change, as we previously didn't mask out additional bits for `fmo`, and `NoTsanAtomic` call. But from implementation it's clear that they are expecting exact enum.
