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

[ppc64] Enable sibling call optimization on ppc64 ELFv1/ELFv2 abi This patch enable sibling call optimization on ppc64 ELFv1/ELFv2 abi, and add a couple of test cases. This patch also passed llvm/clang bootstrap test, and spec2006 build/run/result validation. Original issue: https://llvm.org/bugs/show_bug.cgi?id=25617 Great thanks to Tom's (tjablin) help, he contributed a lot to this patch. Thanks Hal and Kit's invaluable opinions!
