The register set for LDMIA begins at offset 3, not 4. We were previously missing the short encoding of this instruction in the case where the base register was the first register in the register set. Also clean up some dead code: - The isARMLowRegister check is redundant with what VerifyLowRegs does; replace with an assert. - Remove handling of LDMDB instruction, which has no short encoding (and does not appear in ReduceTable).
