This implements codegen support for accesses to thread-local variables
using the local-dynamic model, and adds a clean-up pass so that the base
address for the TLS block can be re-used between local-dynamic access on
an execution path.

This fixes a TODO from 2007 :) Previously, LLVM would emit the wrong
code here (see the update to test/CodeGen/X86/tls-pie.ll).

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

In the case of EDInstInfo, this would actually cause a bug when -1 became 255
and was then compared >=0 in llvm-mc/Disassembler.cpp.
