27bb8d0a88 Added VCVT (between floating-point and fixed-point, VFP) for disassembly. 
A8.6.297

c9745049e6 Added VMRS/VMSR for disassembly only. 
A8.6.335 & A8.6.336

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

A8.6.300


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95669 91177308-0d34-0410-b5e6-96231b3b80d8

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.

A8.6.295

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.
