benchtests: Add fmax/fmin benchmarks
This patch adds fmax and fmin benchtests. It is based 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 fmin and fmax. (CFLAGS-bench-fmax.c): New rule. (CFLAGS-bench-fmin.c): New rule. * benchtests/fmax-inputs: New file. * benchtests/fmin-inputs: Likewise.
