Hans Wennborg ab8b2f1f64 Merge r242733, r242734, r242735 and r242742 ...

(r242742 is the interesting patch here, but I picked the others too to get a clean
 merge since there's been some back-and-forth on this file.)

ARMLoadStoreOptimizer: Create LDRD/STRD on thumb2

Re-apply r241926 with an additional check that r13 and r15 are not used
for LDRD/STRD. See http://llvm.org/PR24190. This also already includes
the fix from r241951.
