Adhemerval Zanella f165e244e4 math: Simplify and optimize modf implementation 
Refactor the generic implementation to use math_config.h definitions,
and add an alternative one if the ABI supports truncf instructions
(gated through math-use-builtins-trunc.h).

The generic implementation generates similar code on x86_64, while
the optimization one for aarch64 (where truncf is supported as a
builtin by through frintz), the improvements are:

reciprocal-throughput           master    patch    difference
workload-0_1                    3.0595   3.0698        -0.34%
workload-1_maxint               5.1747   3.0542        40.98%
workload-maxint_maxfloat        3.4391   3.0349        11.75%
workload-integral               3.2732   3.0293         7.45%

latency                         master    patch    difference
workload-0_1                    3.5267   4.7107       -33.57%
workload-1_maxint               6.9074   4.7282        31.55%
workload-maxint_maxfloat        3.7210   4.7506       -27.67%
workload-integral               3.8634   4.8137       -24.60%

Checked on aarch64-linux-gnu and x86_64-linux-gnu.
