Sanjay Patel 80150ed05d [DAG] use SDNode flags 'nsz' to enable fadd/fsub with zero folds ... As discussed in D24815, let's start the process of killing off the broken fast-math global state housed in TargetOptions and eliminate the need for function-level fast-math attributes. Here we enable two similar folds that are possible when we don't care about signed-zero: fadd nsz x, 0 --> x fsub nsz 0, x --> -x Note that although the test cases include a 'sin' function call, I'm side-stepping the FMF-on-calls question (and lack of support in the DAG) for now. It's not needed for these tests - isNegatibleForFree/GetNegatedExpression just look through a ISD::FSIN node. Also, when we create an FNEG node and propagate the Flags of the FSUB to it, this doesn't actually do anything today because Flags are silently dropped for any node that is not a binary operator.
