[InstSimplify] fold 'fcmp nnan oge X, 0.0' when X is not negative This re-raises some of the open questions about how to apply and use fast-math-flags in IR from PR38086: https://bugs.llvm.org/show_bug.cgi?id=38086 ...but given the current implementation (no FMF on casts), this is likely the only way to predicate the transform. This is part of solving PR39475: https://bugs.llvm.org/show_bug.cgi?id=39475 Differential Revision: https://reviews.llvm.org/D53874 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@345725 91177308-0d34-0410-b5e6-96231b3b80d8
