8007165688 Add support for breaking 256-bit int VETCC into two 128-bit ones, 
avoding scalarization of the compare. Reduces code from 59 to 6
instructions. Fix PR10712.

e6083b67c2 Remove DEFINE_TRANSPARENT_CASTED_OPERAND_ACCESSORS, folding its 
functionality into DEFINE_TRANSPARENT_OPERAND_ACCESSORS. A side-effect
of this is that the operand accessors for Constants will tolerate NULL
operands, fixing PR10663.

6f25e6a0ec utils/lit/lit/TestingConfig.py: Pass TEMP and TMP to tests on Win32 hosts. 
Win32 GetTempPath() tends to pick up %WINDIR% when neither TEMP nor TMP was found. %WINDIR% should not be treated writable on recent Windows OS.

0bfea70d09 With the fix in r138164: "Add <imp-def> operands to QQ and QQQQ stack loads."

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.

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.
