Matt Arsenault bc7384fc93 DAG: Change behavior of fminnum/fmaxnum nodes 
Introduce new versions that follow the IEEE semantics
to help with legalization that may need quieted inputs.

There are some regressions from inserting unnecessary
canonicalizes when these are matched from fast math
fcmp + select which should be fixed in a future commit.
