[libcxxabi] Refactor pthread usage into a separate API
This patch refactors all pthread uses of libc++abi into a separate API. This
is the first step towards supporting an externlly-threaded libc++abi library.
I've followed the conventions already used in the libc++ library for the same
purpose.

Recommit r282692: [libc++abi] Use fallback_malloc to allocate __cxa_eh_globals in case of dynamic memory exhaustion.
Throwing an exception for the first time may lead to call calloc to
allocate memory for __cxa_eh_globals. If the memory pool is exhausted
at that moment, it results in abnormal termination of the program.
This patch addresses the issue by using fallback_malloc in that case.
In this revision, some restrictions were added into the test to not
run it in unsuitable environments.

Add a descriptive name for a constant. Also I'm at least temporarily waging war on throw specs, both old and new style. Except where we have already publicly exposed the throw spec, I'm getting rid of them. They may come back later. But they seem somewhat prone to cyclic dependencies here. The throw spec implies compiler generated code that this library has to jump to during stack unwinding. I'd like to minimize the possiblity that the code used to properly make that jump is itself creating such jumps.

By changing all of the throw() specs to noexcept I've been able to compile and link all of the source files into a dylib. Prior to this substitution the changed functions were calling __cxa_call_unexpected which isn't implemented yet. However in none of these cases do we actaully want __cxa_call_unexpected to be called. Primative buildit script added.

A lot of the code in cxa_exception.cpp depends on __cxa_get_globals_fast() returning null if __cxa_get_globals() hasn't been called yet. However it doesn't reliably do that, at least on OS X if __cxa_get_globals_fast() is called prior to pthread_key_create() running. Our choice is to either limit our use of __cxa_get_globals_fast() more than we have, or to have __cxa_get_globals_fast() initialize with pthread_key_create() if necessary. I chose the latter, and replaced pthread_once with a C++11 local static (which should do the same thing).
