ExecuteFunctionUnix.cpp which is guarded by this check should reliably work on darwin as it only uses POSIX API - nothing specific to linux.

_Exit(3) is a fairly simple syscall wrapper whereas exit(3) calls atexit-registered functions + whole lot of stuff that require support for sync primitives. Splitting the tests allows testing the former easily (especially for new port projects) Signed-off-by: Shreeyash Pandey <shreeyash335@gmail.com>

This patch adds support for clock_gettime for Darwin. Darwin syscall 'gettimeofday' is used to query the time from the system. Many headers in llvm-libc-types, namely clockid_t, struct_timespec, struct_timeval, suseconds_t, time_t_32, time_t_64, are modified to include header guards as Darwin has its own implementation of primitive types.
This patch adds a basic implementation/wrapper for mutex using the underlying os_unfair_lock API that macos provides.
