armemu: Implement SMLALD/SMLSLD

armemu: Fix GE/Q flag setting semantics

Stubbed IsSdmcWriteable to always return writeable.

armemu: Correctly set the Q flag for a bunch of ops.

They were setting the old S flag.

armemu: Fix retrieval of the CPSR in MRS instructions.

armemu: Emulate the GE and Q flags.

Needs to use the updated state of the CPSR.

Clean up CMake library specification

dyncom: Move over QADD16/QASX/QSAX/QSUB16

More warning cleanups

CMake: Turn MSVC optimizations up to 11

dyncom: Move SEL over

CFG: Implemented the GetConfigInfoBlk2 function.

dyncom: Move over SASX/SSAX/SADD16/SSUB16

Hopefully this will make people stop thinking it's a hard dependency.

While not having a noticeable effect on CPU-bound applications, this
change gives an about 30-50% increase in performance for games using
the GPU.

Moved most of the shared CFG code there, implemented a few CFG:I functions
