[PATCH] Testsuite: add simple vector divide test

[Josh Conner <jconner at apple dot com>]

The attached test case matches a failure we were seeing on the Apple gcc
compiler which has been fixed in FSF gcc since 4.0.2 (as a result of the
patch for PR c++/10611).  Since the failure behavior (ICE) had no
corresponding test in the suite, it was suggested that I submit this to
mainline.  Geoff Keating approved this off-line, so unless there are any
concerns raised in the next 24 hours, I'll go ahead and check it in.

FWIW, I verified this test against mainline gcc on these targets:
  powerpc-apple-darwin
  i386-apple-darwin
  i686-pc-linux-gnu

Thanks -

Josh
