Adhemerval Zanella 79bfbc93de powerpc: Remove modf optimization 
The generic implementation is slight more optimized than the powerpc
one, where it has a more optimized inf/nan check (by not using FP
unit checks, along with branch prediction hints), and removed one
branch by issuing trunc instead of a combination of floor/ceil (which
also generated less code).

On power10 with gcc 14.2.1:

reciprocal-throughput        master         patch        difference
workload-0_1                 1.1351        0.9067            20.12%

workload-maxint_maxfloat     1.5038        0.9076            39.65%
workload-integral            1.1280        0.9111            19.23%

latency                      master         patch        difference
