Benjamin Kramer 74de08031f [ManagedStatic] Avoid putting function pointers in template args. 
This is super awkward, but GCC doesn't let us have template visible when
an argument is an inline function and -fvisibility-inlines-hidden is
used.

Benjamin Kramer ca693ed79b Don't destroy ManagedStatics in a unit test. 
Turns out this is very hostile towards other unit tests running in the
same process, it unregisters all flags.

Benjamin Kramer 2a441a52df Try to work around MSVC being buggy. Attempt #1. 
error C2971: 'llvm::ManagedStatic': template parameter 'Creator': 'CreateDefaultTimerGroup': a variable with non-static storage duration cannot be used as a non-type argument

Benjamin Kramer 1533eda111 [ManagedStatic] Add a way to pass custom creators/deleters. 
Also add a test case verifying that nested ManagedStatics work correctly.

Chandler Carruth 39cd216f8f Re-apply r211287: Remove support for LLVM runtime multi-threading. 
I'll fix the problems in libclang and other projects in ways that don't
require <mutex> until we sort out the cygwin situation.

NAKAMURA Takumi 104e5f67e2 Revert r211287, "Remove support for LLVM runtime multi-threading." 
libclang still requires it on cygming, lack of incomplete <mutex>.

Zachary Turner 9c9710eaf4 Remove support for LLVM runtime multi-threading. 
After a number of previous small iterations, the functions
llvm_start_multithreaded() and llvm_stop_multithreaded() have
been reduced essentially to no-ops.  This change removes them
entirely.

Nick Lewycky fe856110aa Add support for tsan annotations (thread sanitizer, a valgrind-based tool). 
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!
