[SystemZ] Fix expansion of ISD::FPOW and ISD::FSINCOS The ISD::FPOW and ISD::FSINCOS opcodes default to Legal, but there is no legal instruction for those on SystemZ. This could cause LLVM internal errors. Fixed by setting the operation action to Expand for those opcodes. Also added test cases for all other LLVM IR intrinsics that should generate a library call. (Those already work correctly since the default operation action is fine.) llvm-svn: 248180

; Test that combined sin/cos library call is emitted when appropriate
[SelectionDAG] Allow sin/cos -> sincos optimization on GNU triples w/ just -fno-math-errno Summary: This change enables the sin(x) cos(x) -> sincos(x) optimization on GNU target triples. This optimization was being inhibited when -ffast-math wasn't set because sincos in GLibC does not set errno, while sin and cos do. However, this optimization will only run if the attributes on the sin/cos calls include readnone, which is how clang represents the fact that it doesn't care about the errno values set by these functions (via the -fno-math-errno flag).
