[PATCH, MIPS] Add SIGRIE instructions for MIPS R6

[PATCH, MIPS] Add SIGRIE instructions for MIPS R6

[Robert Suchanek]

Hi,

This patch adds SIGRIE instruction that was introduced in MIPS R6 architecture.

Documentation for the new instruction can be found in "The MIPS32 Instruction Set v6.02"
document available from:

http://imgtec.com/mips/architectures/mips32/

Ok to apply?

Regards,
Robert

opcodes/

	* mips-opc.c (mips_builtin_opcodes): Add "sigrie".

gas/testsuite/

	* gas/mips/r6.s: Add tests for "sigrie".
	* gas/mips/r6.d: Check for "sigrie".
	* gas/mips/r6-n32.d: Likewise.
	* gas/mips/r6-n64.d: Likewise.
