[COMMITTED] PowerPC: Add support for RFC02656 - Enhanced Load Store, with Length Instructions

[COMMITTED] PowerPC: Add support for RFC02656 - Enhanced Load Store, with Length Instructions

[Peter Bergner]

The following patch adds support for Power RFC02656 - Enhanced Load Store
with Length Instructions.  When or even if this will ever show up in
hardware is not determined or guaranteed, therefore this is enabled using
the -mfuture gas option.

Peter


opcodes/
	* ppc-opc.c (PPCVSXF): New define.
	(powerpc_opcodes): Add lxvrl, lxvrll, lxvprl, lxvprll, stxvrl,
	stxvrll, stxvprl, stxvprl.

gas/
	* testsuite/gas/ppc/rfc02656.s: New test.
	* testsuite/gas/ppc/rfc02656.d: Likewise.
	* testsuite/gas/ppc/ppc.exp: Run it.
