ee6264c790 Add <imp-def> operands to QQ and QQQQ stack loads. 
This pleases the register scavenger and brings
test/CodeGen/ARM/2011-08-12-vmovqqqq-pseudo.ll a little closer to
working with -verify-machineinstrs.

55c57f07dd VMOVQQQQs pseudo instructions are only created by ARMBaseInstrInfo::copyPhysReg. 
Therefore, rather then generate a pseudo instruction, which is later expanded,
generate the necessary instructions in place.

bfc0c6c1de If we're splitting the landing pad block and assigning it only one predecessor, 
then don't split it a second time, since that block will be dead.

e4127d626e Do not use named md nodes to track variables that are completely optimized. This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly.

ed042d8794 This is not actually unreachable, so don't use llvm_unreachable for it. Since 
the intent seems to be to terminate even in Release builds, just use abort()
directly.

If program flow ever reaches a __builtin_unreachable (which llvm_unreachable is
#define'd to on newer GCCs) then the program is undefined.
