- 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.

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.
