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

[PowerPC] Add support for dcbtst and icbt (prefetch) Adds code generation support for dcbtst (data cache prefetch for write) and icbt (instruction cache prefetch for read - Book E cores only). We still end up with a 'cannot select' error for the non-supported prefetch intrinsic forms. This will be fixed in a later commit. Fixes PR20692. llvm-svn: 216339
