Adding -verify-machineinstrs option to PowerPC tests Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624

WidenVecRes_BUILD_VECTOR must use the first operand's type Because integer BUILD_VECTOR operands may have a larger type than the result's vector element type, and all operands must have the same type, when widening a BUILD_VECTOR node by adding UNDEFs, we cannot use the vector element type, but rather must use the type of the existing operands. Another bug found by llvm-stress. llvm-svn: 185960
