Petar.Avramovic added a comment.

Move change in IRTranslator in another patch, since effects of that change can only be seen when function attributes are inspected during translation of a function that was not first in input file.
Move check for NoNaNsFPMath in isKnownNeverSNaN.
Reduce number of tests, only keep characteristic ones that will be updated when we add some combines and improvements to legalizer. Later switch to existing test in sdag that also checks for pattern commutes.
