llvm-6502/test/CodeGen/Thumb2/2009-09-28-ITBlockBug.ll
Evan Cheng b9803a8fa6 - Add pseudo instructions tLDRpci_pic and t2LDRpci_pic which does a pc-relative 
load of a GV from constantpool and then add pc. It allows the code sequence to
  be rematerializable so it would be hoisted by machine licm.
- Add a late pass to break these pseudo instructions into a number of real
  instructions. Also move the code in Thumb2 IT pass that breaks up t2MOVi32imm
  to this pass. This is done before post regalloc scheduling to allow the
  scheduler to proper schedule these instructions. It also allow them to be
  if-converted and shrunk by later passes.
