[arm][simulator] Break up Advanced SIMD data processing instructions

These correspond to the SpecialValue 4 and 6, I extracted them out into
their own section, following the decoding guide in the manual (and used
in the disassembler).

Mostly copy paste, actual code changes limited to breaking up logic for
separate opcodes so they end up in different clauses.
