27bb8d0a88 Added VCVT (between floating-point and fixed-point, VFP) for disassembly.

2d658df873 Added vcvtb/vcvtt (between half-precision and single-precision, VFP).
For disassembly only.

15b423f772 Add VCVTR (between floating-point and integer, VFP) for disassembly purpose.
The 'R' suffix means the to-integer operations use the rounding mode specified
by the FPSCR, encoded as Inst{7} = 0.

69a8c7f497 Modified encoding bits specification for VFP instructions. In particular, the D
bit (Inst{22}) and the M bit (Inst{5}) should be left unspecified.  For binary
format instructions, Inst{6} and Inst{4} need to specified for proper decodings.
