d457e6e9a5 Refactor code. Fix a potential missing check. Teach isIdentical() about tLDRpci_pic.

78e5c1140a - Add TargetInstrInfo::isIdentical(). It's similar to MachineInstr::isIdentical 
except it doesn't care if the definitions' virtual registers differ. This is
  used by machine LICM and other MI passes to perform CSE.
- Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical.
  Since pc relative constantpool entries are always different, this requires it
  it check if the values can actually the same.

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.

54c78ef2fe Print VMOV (immediate) operands as hexadecimal values. Apple's assembler 
will not accept negative values for these.  LLVM's default operand printing
sign extends values, so that valid unsigned values appear as negative
immediates.  Print all VMOV immediate operands as hex values to resolve this.

50608bac2f RangeIsDefinedByCopyFromReg() should check for subreg_to_reg, insert_subreg, 
and extract_subreg as a "copy" that defines a valno.
Also fixes a typo. These two issues prevent a simple subreg coalescing from
happening before.

72ed88feac Initilize the machine LICM CSE map upon the first time an instruction is hoisted to 
the loop preheader. Add instructions which are already in the preheader block that
may be common expressions of those that are hoisted out. These does get a few more
instructions CSE'ed.

43f44aa160 improve x86 codegen support for blockaddress. We now compile 
the testcase into:

_test1:                                                     ## @test1
## BB#0:                                                    ## %entry
	leaq	L_test1_bb6(%rip), %rax
	jmpq	*%rax
L_test1_bb:                                                 ## Address Taken
LBB1_1:                                                     ## %bb
	movb	$1, %al
	ret
L_test1_bb6:                                                ## Address Taken
LBB1_2:                                                     ## %bb6
	movb	$2, %al
	ret

Note, it is very very strange that BlockAddressSDNode doesn't carry 
around TargetFlags.  Dan, please fix this.
