pthread_self() returns a pthread_t, but we were setting it to
an int. It seems the cast to int when calling sysctl is still
the correct thing to do, though.

Applications often need the current thread id when making
system calls, and some operating systems provide the notion
of a thread name, which can be useful in enabling better
diagnostics when debugging or logging.
This patch adds an accessor for the thread id, and "best effort"
getters and setters for the thread name. Since this is
non critical functionality, no error is returned to indicate
that a platform doesn't support thread names.

This reverts commit r221331 and reinstate r220932 as discussed in D19271.
Original commit message was:
This patch adds an llvm_call_once which is a wrapper around
std::call_once on platforms where it is available and devoid
of bugs. The patch also migrates the ManagedStatic mutex to
be allocated using llvm_call_once.
These changes are philosophically equivalent to the changes
added in r219638, which were reverted due to a hang on Win32
which was the result of a bug in the Windows implementation
of std::call_once.

Commit 220932 caused crash when building clang-tblgen on aarch64 debian target,
so it's blocking all daily tests.
The std::call_once implementation in pthread has bug for aarch64 debian.
