ff79d7d1 - InstCombine: Apply demanded mask at recursion limit in SimplifyDemandedFPClass (#178157)

InstCombine: Apply demanded mask at recursion limit in SimplifyDemandedFPClass (#178157) This fixes missed flag inference in some cases, due to not inferring no-nan result implies no-nan source. Also start treating explicit nofpclass attributes as a leaf value, like a constant or argument.
