Thumb unconditional branches are allowed in IT blocks, and therefore should have a predicate operand, unlike conditional branches.

Make the SelectionDAG verify that all the operands of BUILD_VECTOR have the same type.  Teach DAGCombiner::visitINSERT_VECTOR_ELT not to make invalid BUILD_VECTORs.  Fixes PR10897.

In some cases such as interpreters using indirectbr, the CFG can be very
complicated, and live range splitting may be forced to insert a large
number of phi-defs.  When that happens, traceSiblingValue can spend a
lot of time zipping around in the CFG looking for defs and reloads.

This patch causes more information to be cached in SibValues, and the
cached values are used to terminate searches early.  This speeds up
spilling by 20x in one interpreter test case.  For more typical code,
this is just a 10% speedup of spilling.

The previous version had bugs that caused miscompilations. They have
been fixed.

have redundant eh.typeid.for tests be eliminated in the presence of
cleanups.

Fix handling of Intel syntax disassembling of movs and stos to stop being blank. Also fixed scas, and cmps to always print size suffix in Intel syntax since its abiguous without arguments. Fixes PR10875.

This change and the ones that follow have been discussed with and approved by

Directly point debug info to the stack slot of the arugment, instead of trying to keep track of vreg in which it the arugment is copied. The LiveDebugVariable can keep track of variable's ranges.
