VFP: Minor cleanup, functionally the same.

dyncom: Implement REVSH

Also joins the REV ops into one common place.

dyncom: Implement SMLALD/SMLSLD

Implemented the SaveDataCheck archive

dyncom: Implement SMMLA/SMMUL/SMMLS

Fixed a few warnings and cleaned up the code

This allows Steel Diver to boot further, some files are needed.

This is still not ready and needs a big cleanup, this will possibly be delayed until the way we handle archives is fixed (with factory classes instead of ahead-of-time creation of archives)

archive/elf: Minor misc changes.

dyncom: Implemented LDREXD/STREXD/LDREXH/STREXH

dyncom: Remove dead function InterpreterInitInstLength

dyncom: Implement SMLAD/SMUAD/SMLSD/SMUSD

soc_u: Fix a missing formatting argument

Technically eliminates two memory leaks as well.

dyncom: Implement SXTAB16 and SXTB16

Qt: Letter cases and single window mode

pica_progress followups

dyncom: Implement SHADD8/SHADD16/SHSUB8/SHSUB16/SHASX/SHSAX

dyncom: Implement SADD8/SSUB8

In various menu options letter cases were not consistent. This was also
the case within various debugging widgets. This attempts to make letter
cases consistent, but it is of course a matter of opinion which way is the
correct one.

Set object name for the Graphics Debugger

Setting an object name for GPUCommandStreamWidget allows for saving the
graphics debugger's state (if it's show, position, etc). This state is
then restored when restarting the application.
