PR target/65240
* config/rs6000/predicates.md (easy_fp_constant): Remove special
-ffast-math handling that kept non-0 constants live in the RTL
until reload. Remove logic testing the number of instructions it
took to create a constant in a GPR that was never used, due to a
test for soft-float earlier.
(memory_fp_constant): Delete, no longer used.
* config/rs6000/rs6000.md (mov<MODE>_hardfloat): Remove
alternatives for loading non-0 constants into GPRs for hard
floating point that is no longer needed due to changes in
easy_fp_constant. Add support for loading 0.0 into GPRs.
(mov<mode>_hardfloat32): Likewise.
(mov<mode>_hardfloat64): Likewise.
(mov<mode>_64bit_dm): Likewise.
(movtd_64bit_nodm): Likewise.
(pre-reload move FP constant define_split): Delete define_split,
since it is no longer used.
(extenddftf2_internal): Remove GHF constraints that are not valid
for extenddftf2.
