Hello,
this patch lets some predicates on floating point constants answer true for
vectors, so optimizations are applied.
Tested bootstrap + testsuite (default languages).
Ok. Bonus points if you quickly eyed users of whether they may be surprised
in vectors coming through now.
I did (that's why I didn't also change integer_twop), but I won't claim
the bonus points, because in fold-const.c:
* there is probably an issue with signed zero in fold_real_zero_addition_p
* the RDIV_EXPR case would like real_zerop to mean "at least one is zero"
* abs(x)>=0 or <0 doesn't seem ready
but that's not much compared to the broken integer vector optimizations
