[PATCH] Add benchtests for roundeven and roundevenf.

[Shen-Ta Hsieh <ibmibmibm dot tw at gmail dot com>]

This patch adds benchtests for the roundeven and roundevenf functions.  The
inputs are copied from trunc-inputs.

        * benchtests/Makefile (bench-math): Add roundeven and roundevenff.
        * benchtests/roundeven-inputs: New file.
        * benchtests/roundevenf-inputs: Likewise.
