[patch][commit] MeP CPU Description

Dave Brolley-2
Hi,

I've committed the attached to the cgen .cpu description for the MeP
port. This change allows gcc to correctly identify the required argument
types for its internally-generated intrinsic builtin functions for each
insn. The change causes a cosmetic change to opcodes/mep-desc.c, when
regenerated, which I have also committed.

Dave
