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

[APFloat] Switch from (PPCDoubleDoubleImpl, IEEEdouble) layout to (IEEEdouble, IEEEdouble) Summary: This patch changes the layout of DoubleAPFloat, and adjust all operations to do either: 1) (IEEEdouble, IEEEdouble) -> (uint64_t, uint64_t) -> PPCDoubleDoubleImpl, then run the old algorithm. 2) Do the right thing directly. 1) includes multiply, divide, remainder, mod, fusedMultiplyAdd, roundToIntegral, convertFromString, next, convertToInteger, convertFromAPInt, convertFromSignExtendedInteger, convertFromZeroExtendedInteger, convertToHexString, toString, getExactInverse. 2) includes makeZero, makeLargest, makeSmallest, makeSmallestNormalized, compare, bitwiseIsEqual, bitcastToAPInt, isDenormal, isSmallest, isLargest, isInteger, ilogb, scalbn, frexp, hash_value, Profile. I could split this into two patches, e.g. use 1) for all operatoins first, then incrementally change some of them to 2). I didn't do that, because 1) involves code that converts data between PPCDoubleDoubleImpl and (IEEEdouble, IEEEdouble) back and forth, and may pessimize the compiler. Instead, I find easy functions and use approach 2) for them directly. Next step is to implement move multiply and divide from 1) to 2). I don't have plans for other functions in 1).
