[committed] mips.md macroisation (8/n)

[Richard Sandiford]

Part 8 of the mips.md macroisation process.  This patch handles the
MIPS16 $31 store patterns.

Bootstrapped & regression tested on mips-sgi-irix6.5.  Also tested by
comparing the gcc.c-torture and gcc.dg output of "mips64-elf -O2 -mips16"
before and after the patch.  Applied to head.

	* config/mips/mips.md (*mov<mode>_ra): Name previously unnamed MIPS16
	$31 store insns.  Redefine using :GPR.
