the machine instruction representation of the immediate value to be encoded into an integer with similar fields as the actual VMOV instruction. This makes things easier for the disassembler, since it can just stuff the bits into the immediate operand, but harder for the asm printer since it has to decode the value to be printed. Testcase for the encoding will follow later when MC has more support for ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105836 91177308-0d34-0410-b5e6-96231b3b80d8
