[Bug math/3325] New: Implementation of fpmod should use fprem1, not fprem

["jaredcasper at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

According to Vol 2A of the IA-32 Intel® Architecture Software Developer?s Manual
(http://download.intel.com/design/Pentium4/manuals/25366620.pdf) page 3-355, the
fprem1 instruction follows IEEE Std. 754, and the fprem instruction does not (it
is an old implementation they kept around for backward compatibility).   So it
seems like the __ieee754_fmod* instructions in sysdeps/i386/fpu/e_fmod* should
use fprem1, not fprem.
