I needed one small addition - posix_memalign is not available on the
earliest Darwin versions that are regularly tested - but the malloc there
is guaranteed to be sufficiently aligned for the largest vectors in use.

tested on *-darwin*, x86_64-linux-gnu and powerpc-aix.
pushed to master, thanks

[pushed] testsuite, Darwin: In tsvc.h, use malloc for Darwin <= 9.

Earlier Darwin versions fdo not have posix_memalign() but the
malloc implementation is guaranteed to produce memory suitably
aligned for the largest vector type.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/tsvc/tsvc.h: Use malloc for Darwin 9 and
	earlier.
