Add benchtests for trunc and truncf.
This patch adds benchtests for the trunc and truncf functions. The inputs listed are fairly arbitrary; I do not assert they are representative of any particular application. * benchtests/Makefile (bench-math): Add trunc and truncf. (CFLAGS-bench-trunc.c): New variable. (CFLAGS-bench-truncf.c): Likewise. * benchtests/trunc-inputs: New file. * benchtests/truncf-inputs: Likewise.
