* R5900 COP2 is now ready for testing.  Let loose the dogs!

Mon Apr  6 19:55:56 1998  Frank Ch. Eigler  <fche@cygnus.com>

	* interp.c (cop_[ls]q): Replaced stub with proper COP2 code.

	* sim-main.h (LOADADDRMASK): Redefine to allow 128-bit accesses
 	for TARGET_SKY.

	* r5900.igen (SQC2): Thinko.
