trapv-vect-reduc-4.c.133t.vect

Between 20150731 and 20150807, a testsuite regression on Solaris/SPARC occured:

FAIL: gcc.dg/vect/trapv-vect-reduc-4.c scan-tree-dump-times vect "vectorized 2
loops" 1

It happens for both 32 and 64-bit and was probably introduced by this patch:

2015-08-01  Tom de Vries  <tom@codesourcery.com>
[...]
        * gcc.dg/vect/trapv-vect-reduc-4.c: Update scan to match vectorized min
        and max reductions.
