Maciej W. Rozycki May 29, 2021, 1:37 a.m.
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", 
	"r5900", "r6000", "rm7000", "rm9000", "r8000", "r10000", 
	"r12000", "r14000", "r16000", "mips5", "loongson2e", and
	"loongson2f".

	gas/
	* testsuite/gas/mips/cp1-names-r3900.d: New test.
	* testsuite/gas/mips/mips.exp: Run the new test.
	* testsuite/gas/mips/branch-misc-3.d: Update disassembly 
	according to changes to opcodes.
	* testsuite/gas/mips/cp1-names-r3000.d: Likewise.
	* testsuite/gas/mips/cp1-names-r4000.d: Likewise.
	* testsuite/gas/mips/relax-swap1-mips1.d: Likewise.
	* testsuite/gas/mips/relax-swap1-mips2.d: Likewise.
	* testsuite/gas/mips/trunc.d: Likewise.
