c8897d9c2f Restore other bits of the C API that I tore up. All pre-existing APIs default to using the 
default global context, while new *InContext() APIs have been added that take a LLVMContextRef parameter.

Apologies to anyone affected by this breakage.

334143d304 I give up on trying to use reader/writer locks for recursive type refinement. Use a recursive mutex instead, which will (in theory) generate more contention, but is really 
a much more natural fit for what's going on during recursive type refinement.

8b477ed579 Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

constant and type uniquing tables.  For now, just make it a wrapper around the existing APIs.

1970a89a49 Call doInitialization(), releaseMemory(), and doFinalization() for on-the-fly passes as well. 
Also don't call finalizers for LoopPass if initialization was not called.
Add a unittest that tests that these methods are called, in the proper
order, and the correct number of times.

6b96f6cfeb Guard the listeners list. Unfortunately, this requires a real static rather 
than a managed static because other managed statics can (and do) access this
list in their destructors.  Yes, I know it's horrible.

04fb7c36a9 Revert r73790, and replace it with a significantly less ugly solution. Rather than trying to make the global reader-writer lock work, 
create separate recursive mutexes for each value map.  The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.

430444b102 Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation 
gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.
