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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73801 91177308-0d34-0410-b5e6-96231b3b80d8
