Pseudo-ize Thumb2 jump tables with explicit MC lowering to the raw

Encode the multi-load/store instructions with their respective modes ('ia',
...
'db', 'ib', 'da') instead of having that mode as a separate field in the
instruction. It's more convenient for the asm parser and much more readable for
humans.

The MC code couldn't handle ARM LDR instructions with negative offsets:
...
vldr.64 d1, [r0, #-32]
The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

hook up getOpcodeName for ARM so that "llc -show-mc-inst" includes

the opcode string in the inst dump, e.g.:
vmov r2, r3, d17 @ encoding: [0x31,0x2b,0x53,0xec]

@ <MCOperand Reg:68>
@ <MCOperand Reg:69>
