New Revision: 90173

URL: http://llvm.org/viewvc/llvm-project?rev=90173&view=rev
Log:
For VMOV (immediate), make some of the encoding bits (cmode and op) unspecified.
For VMOVv*i[16,32], op bit is don't care, and some cmode bits vary depending on
the immediate values.

Ref: Table A7-15 Modified immediate values for Advanced SIMD instructions.
