Sanjay Patel cc0615ad0a propagate IR-level fast-math-flags to DAG nodes (NFC) ... This patch adds the minimum plumbing necessary to use IR-level fast-math-flags (FMF) in the backend without actually using them for anything yet. This is a follow-on to: http://reviews.llvm.org/rL235997 ...which split the existing nsw / nuw / exact flags and FMF into their own struct. There are 2 structural changes here: 1. The main diff is that we're preparing to extend the optimization flags to affect more than just binary SDNodes. Eg, IR intrinsics ( https://llvm.org/bugs/show_bug.cgi?id=21290 ) or non-binop nodes that don't even exist in IR such as FMA, FNEG, etc. 2. The other change is that we're actually copying the FP fast-math-flags from the IR instructions to SDNodes.
