change TLS_ADDR lowering to lower to a real mem operand, instead of matching as
...
a global with that gets printed with the :mem modifier. All operands to lea's
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this. There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).
This also makes the use of EBX explicit in the operand list in the 32-bit,
instead of implicit in the instruction.

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
