* gas/config/tc-arm.c (parse_vfp_reg_list): Improve register bounds

	* gas/config/tc-arm.c (parse_vfp_reg_list): Improve register bounds
	checking.
	(do_neon_mov): Enable several VMOV variants for VFP. Add suitable
	architecture version checks.
	(insns): Allow overlapping instructions to be used in VFP mode.

   	* gas/testsuite/gas/arm/vfp-neon-overlap.s: New test. Overlapping
	VFP/Neon instructions.
	* gas/testsuite/gas/arm/vfp-neon-overlap.d: Expected output of above.
	* gas/testsuite/gas/arm/vfp1xD.d: Test for fldmx/fstmx.
	* gas/testsuite/gas/arm/vfp1xD_t2.d: Likewise.
	* gas/testsuite/gas/arm/vfpv3-32drs.d: Likewise.

   	* opcodes/arm-dis.c (coprocessor_opcodes): Don't interpret fldmx/fstmx
	as vldm/vstm.
