Can eqne pattern removal patches be committed firstly?

Please first make sure you test with corner cases, NaNs in
particular.  I'm pretty sure we don't have any test cases for
those.

But isn't canonicalization of EQ/NE safe, even for IEEE NaN and +-0.0?

target = (a == b) ? x : y
target = (a != b) ? y : x

Are equivalent, even for IEEE IIRC.
