[mips, committed] Fix a micromips test for n32 targets

[Richard Sandiford]

micromips-warn-branch-delay.d failed on mips64*-linux-gnu targets
because $13 is t1 rather than t5 for n32.  Fixed by using numeric
registers instead.

Tested on various targets and applied.

	* gas/mips/micromips-warn-branch-delay.d: Use numeric registers.
