ae1b99e42d Grrr. The mn10200 and mn10300 are _not_ similar enough to easily support
with a single generic configuration.  So break them up into two different
configurations.  See the individual ChangeLogs for additional detail.

	(load_register): Ensure hi32 bits are not lost during lo32bit
 	processing. Fix shift offset that was overflowing into the next

Fri Sep  6 18:23:54 1996  James G. Smith  <jsmith@cygnus.co.uk>

	* 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.
