* genopinit.c (optabs): Use smin/smax for floating point too.
* doc/md.texi: Update to match. Clarify that floating point
results are undefined for +0/-0 and NaN.
* doc/rtl.texi: Likewise.
* rtl.def (SMIN, SMAX): Likewise
* tree.def (MIN_EXPR, MAX_EXPR): Likewise.
* config/alpha/alpha.md (smaxdf3, smindf3, smaxsf3, sminsf3): Add
leading 's' to the name.
* config/ia64/ia64.md (smaxsf3, sminsf3, smaxdf3, smindf3,
smaxxf3, sminxf3): Likewise.
* config/rs6000/rs6000.md (smaxdf3, smindf3, smaxsf3, sminsf3):
Likewise.
