Sam McCall e0a3dec9fb [clangd] Use pthread instead of thread_local to support more runtimes. 
Summary:
thread_local has nice syntax and semantics, but requires __cxa_thread_atexit,
and some not-ancient runtime libraries don't provide it.
The clang-x86_64-linux-selfhost-modules buildbot is one example :-)

It works on windows, and the other platforms clang-tools-extra supports should
all have the relevant pthread API. So we just use that if it's available,
falling back to thread_local (so if a platform has neither, we'll fail to link).

The fallback should really be the other way, that would require cmake changes.

libcxx Add static_asserts to basic_ios and basic_stream_buf to ensure that that the traits match the character type. This is a requirement on the user - now we get consistent failures at compile time instead of incomprehensible error messages or runtime failures.
