[patch, testsuite] vect_no_align testsuite failures


This patch fixes the gcc.dg/vect/vect-42.c and
gcc.dg/vect/no-vfa-vect-43.c failures on IA64 (HP-UX and Linux).  They
have been failing since r147851 when the compiler was changed to fix
PR tree-optimization/36327 and these tests were modified.  I don't think
the test modifications that were made took vect_no_align compilers into
account.

Tested on IA64 HP-UX and Linux, this could also affect (hopefully for
the better) other vect_no_align systems such as sparc, mipsisa64, and
arm32.  I see these tests show up as failures for some arm results
in gcc-testresults so this patch should fix those failures too.

	* gcc.dg/vect/vect-42.c: Modify vect_no_align case.
	* gcc.dg/vect/no-vfa-vect-43.c: Ditto.
