The lo and hi parts of the result were being constructed as a result of hi and lo halfword intermixing from the rm and rn regs. However the lo part of the result should be constructed only from the lo halfwords of rm and rn, and the hi part of the result should only be constructed from the hi halfwords of rm and rn.

Join SMUAD, SMUSD, and SMLAD ops. Also fix them as well.

armemu: Backport some VFP fixes from 3dmoo.

Wrong values were being multiplied together.

Comment out empty arrays causing compile errors in MSVC

armemu: Implement UXTAB16

Archive refactor

- Refactor FS::Archive internals to make Archive creation and lifetime
  management clearer.

Fix spelling mistakes.

Added stubs for ldr:ro, cecd:u, nim:aoc, and am:app services

armemu: Fix UXTB16

Remove SyncRequest from K::Object and create a new K::Session type

I couldn't find any information about this service...

Apparently nothing at all is known about this service...

This is a first step at fixing the conceptual insanity that is our

derived from Session because we don't have the infrastructure to do it
properly. (That is, Processes and scheduling them.)

Rotation bits are 10 and 11, not 9 and 10.

Clean up armdefs.h a little.

SVC: Implemented Semaphores

ARM: Pull some SkyEye fixes from 3dmoo.
