benchtests: Add fmaxf/fminf benchmarks
This patch adds fmaxf and fminf benchtests. It is based on math/s_fmax_template.c implementation which checks for basically four different classes: 1. if x is greater or equal than y. 2. if x is less than y. 3. if x or y is signaling. 4. if y is nan. Cases 1 and 2 are used for default input number (by mixing normal double numbers and infinity), while case 3 and 4 are used each for on for a benchmark class. Checked on x86_64-linux-gnu and powerpc64-linux-gnu. * benchtests/Makefile (bench-math): Add fminf and fmaxf. (CFLAGS-bench-fmaxf.c): New rule. (CFLAGS-bench-fminf.c): Likewise. * benchtests/fmaxf-inputs: New file. * benchtests/fminf-inputs: Likewise.
