[testsuite] [sparc] select ultrasparc for fsmuld test

vis3move-3.c expects fsmuld, that is not available on all variants of
sparc.  Select a cpu that supports it for the test.

Now, -mfix-ut699 irrevocbly disables fsmuld, so skip the test if the
test configuration uses that option.

	* gcc.target/sparc/vis3move-3.c: Select ultrasparc.  Skip with
	-mfix-ut699.
