[Bug target/16324] New: static functions should use 'regparm' to pass arguments by default

["bryner at brianryner dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Since with a static function there's no chance of the function being called from
outside the translation unit where the calling convention isn't known, it would
make sense to always use up to 3 registers to pass parameters to static
functions on x86.  This seems to nearly always generate better code at the call
site.
