rs6000.c (rs6000_float_const): Remove warning.
* config/rs6000/rs6000.c (rs6000_float_const): Remove warning.
(setup_incoming_varargs): Remove warning.
* config/rs6000/rs6000.c (validate_condition_mode): When
flag_fast_math, allow floating-point conditionals to be reversed.
(rs6000_generate_compare): When flag_fast_math, don't generate
cror operations for FP conditionals.
