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.

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,

unlocked versions of most of the code.

convenience.
