Roll r127459 back in: Optimize trivial branches in CodeGenPrepare, which often get created from the lowering of objectsize intrinsics. Unfortunately, a number of tests were relying on llc not optimizing trivial branches, so I had to add an option to allow them to continue to test what they originally tested. This fixes <rdar://problem/8785296> and <rdar://problem/9112893>. llvm-svn: 127498

; CHECK: t:
- 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. llvm-svn: 86304
