Three more cleanups after the unit-related ARM refactoring piled up and
come first in this series. It also fixes (again...) dependencies for
parallel builds. But the actual focus is on something x86-specific:
This introduces a test device and a test inmate for the MMIO instruction
parser we unfortunately need on x86. It identified 4 issues in that
code, fortunately all of them only recently introduced with new
instructions. Besides fixing them, this also completes the handling SIB
bytes and (hopefully) make the parser more palatable for readers.
Future changes to the instruction parser now have to come with test
cases attached. The existing ones may not be complete yet for 64-bit
mode either, needs at least one more careful round of checking - maybe
via gcov as well. We definitely need some 32-bit tests in addition.
