[PATCH] Change llvm::sys::Mutex implementation to use STL-provided mutexes.

[Zachary Turner]

Hi rnk,

Change llvm::sys::Mutex implementation to use std::mutex and std::recursive_mutex.

This patch deletes the platform specific mutex implementations, and delegates to the underlying STL implementation.  Because STL mutex and recursive_mutex are implemented as separate classes, it is no longer possible to specify as a runtime param whether a recursive mutex is desired, and instead the decision must be made at compile time.

As part of this refactor, the ScopedLock class is deleted in favor of MutexGuard, which provides equivalent functionality.
