Add "vmov.<dt> <Qd>, #<imm>" to integrated ARM assembler.

Adds the VMOV instruction to the integrated assembler. Because #<imm> is
complex, and we don't currently have a special ARM class to encode
constants defined by ARM method AdvSIMDExpandImm(), it currently only
accepts (nonnegative) integer32 constants that can fit into 8 bits.

There are no tests for this instruction, since there currently no
callers to this instruction. However, John will be checking in a CL
shortly that will use this instruction.

Add example generator for vector add.
