The Common VFP Subarchitecture specification has two more FP control registers
which are to be accessed through VMRS and VMSR. The assembler, however, so far
didn't provide a way to encode the respective instructions (other than through
legacy mnemonics or the hard to read MRC/MCR ones). As per previous discussion,
accept all control registers here.

	* gas/config/tc-arm.c (do_vmrs): Accept all control registers.
	Use local variable Rt in more places.
	(do_vmsr): Accept all control registers.

	* gas/arm/vfp1xD.s: Add VMRS/VMSR tests with FPINST, FPINST2,
	and C15.
	* gas/arm/vfp1xD.d: Update accordingly.


OK.

R.
