arch-arm: Use VecElem instead of FloatReg for FP instruction

SIMD & FP Operations use FloatRegs in AArch32 mode and VecRegs in
AArch64 mode. The usage of two different register pools breaks
interprocessing between A32 and A64.  This patch is changing definition
of arm operands so that they are backed by VecElems in A32, which are
mapped to the same storage as A64 VecRegs.
