This includes all the obvious bitwise operations (AND, OR, BIC, ORN,
MVN) in register-to-register forms, and the immediate forms of
AND/OR/BIC/ORN; byte-order reverse instructions; and the VMOVs that
access a single lane of a vector.
Some of those VMOVs (specifically, the ones that access a 32-bit lane)
share an encoding with existing instructions that were disassembled as
accessing half of a d-register (e.g. `vmov.32 r0, d1[0]`), but in
8.1-M they're now written as accessing a quarter of a q-register (e.g.
`vmov.32 r0, q0[2]`). The older syntax is still accepted by the
assembler.
