MIPS/opcodes: Add legacy CP1 control register names

The two CP1 control registers defined by legacy ISAs used to be referred
to by various names, such as FCR0, FCR31, FSR, however their documented
full names have always been the Implementation and Revision, and Control
and Status respectively, so the FIR and FCSR acronyms coming from modern
ISA revisions will be just as unambiguous while improving the clarity of
disassembly.  Do not update the TX39 though as it did not have an FPU.

	opcodes/
	* mips-dis.c (mips_cp1_names_mips): New variable.
	(mips_arch_choices): Use it rather than `mips_cp1_names_numeric'
	for "r3000", "r4000", "r4010", "vr4100", "vr4111", "vr4120",
	"r4300", "r4400", "r4600", "r4650", "r5000", "vr5400", "vr5500",
