[PATCH,GAS,ARM] Add missing rfe and srs mnemonics

["Greta Yorsh" <greta dot yorsh at arm dot com>]

This patch adds support for missing mnemonics:
rfe,srs,srsea,srsfa,srsed,srsfd. 
It address a concern raised here:
http://sourceware.org/ml/binutils/2012-12/msg00181.html

This patch also fixes encoding of rfefa,rfeea,rfeed.

It also adds tests for rfe and srs mnemonics.

No regression on qemu for arm-none-eabi gas testsuite.

This patch is for trunk. It would also be good to backport this patch to the
current release branch.

Thanks,
Greta
