[gomp4 5/8] libgomp: provide sem.h, mutex.h, ptrlock.h on nvptx

This patch provides minimal non-stub implementations for libgomp mutex/ptrlock/semaphore, using atomic ops and busy waiting. The goal here is to at least provide stub struct declarations necessary to unbreak libgomp.h. Atomics with busy waiting seems to be the only way to provide such primitives
