The mips msa-ds.c test is trying to ensure that MSA branches can have 
their delay slots filled.  The regexp it used looked for the function 
name, a nop, then the function name again.  If found that sequence, then 
the test failed.

The problem is with Vlad's recent IRA work there's simply less code in 
the test (good) and as a result one of the *other* branches in the test 
had an unfilled delay slot -- the delay slot for the MSA branch was 
still being filled.

This patch tightens up the regexp.  In particular it looks for the MSA 
branch and a nop on the next line (avoiding the over-eager .* 
construct).  That indicates that the MSA branch did not have its delay 
slot filled.  When that sequence is found, then the test fails.


This fixes the recent regressions for mips64 and mips64el in the tester.
