* config/tc-mips.c (COUNT_TOP_ZEROES): Added macro to count
 	leading zeroes.
	(load_register): Ensure hi32 bits are not lost during lo32bit
 	processing. Fix shift offset that was overflowing into the next
 	instruction field. Add code to generate shorter sequences for
 	constants with a single contiguous seqeuence of ones.

	* 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.

Number of	ffs()		for loop	if/then/else	conditional
leading								   ?:
zeroes
