	* gas/mips/dli.{s,d}: More test cases added.

NOTE: The COUNT_TOP_ZEROES macro is a bit bulky, and the same result
can be achieved by using a "standard" ffs() routine:
	count = ffs(~v);
	count = count == 0 ? 0 : 33 - count;

However the following timings (VR4300 CPU clock ticks on a CMA101
board) show the performance gain.
