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.

2017-09-18  Joseph Myers  <joseph@codesourcery.com>

	* 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.
