I'm making progress but have questions for Dorit and others who have
contributed the vect tests:

Tests vect-72.c and vect-73.c use -mpowerpc64.  That has no effect on a
biarch compiler; should it have been -m64?  I always test a biarch
compiler with both -m32 and -m64 anyway so using -m64 in a test would
cause problems, or at least confusion.  There are tests in other parts
of the testsuite that are only relevant for either -m32 or -m64 that
we're trying to figure out how to handle.

There are currently 91 tests in gcc.dg/vect and only 31 of them specify
mipsisa64*-*-* as a target.  Is it an oversight that most of the other
tests are not run for mipsisa64?
