Custom lower the memory barrier instructions and add support for lowering without sse2. Add a couple of new testcases. Fixes a few libgomp tests and latent bugs. Remove a few todos. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109078 91177308-0d34-0410-b5e6-96231b3b80d8 2010-07-22 02:48:34 +00:00			`; RUN: llc < %s -march=x86 -mattr=-sse2 \| grep lock`
