03f6f8e5ee Improve the Threading code on NetBSD
Do not include <sys/user.h> on NetBSD. It's dead file and will be removed.

No need to include <sys/sysctl.h> in this code context on NetBSD.

817f226056 Detect the existence of pthread_{s,g}etname_np in libpthread on Linux
Older Linux distributions may not have those functions.

dd6a386236 Try again to appease the FreeBSD bot.
The actual logic was wrong, not just the type conversion.
This should get it correct.

9f4052c410 Try to appease the FreeBSD bots.
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.

471deac0c7 [Support] Provide access to current thread name/thread id.
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.

f03585d240 Revert "Revert 220932.": "Removing the static initializer in ManagedStatic.cpp by using llvm_call_once to initialize the ManagedStatic mutex"
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.

8d0fd58599 Revert 220932.
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.
