    vect: disable bitmask tests on sparc

The problem is that dg-skip-if must come after dg-do, although this
isn't currently documented unfortunately.

Fixed by reordering the directives.

Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.

	gcc/testsuite:
	* gcc.dg/vect/vect-bic-bitmask-12.c: Move dg-skip-if down.
	* gcc.dg/vect/vect-bic-bitmask-23.c: Likewise.
