Use memory card 251 for games that cannot use large memory cards
add setting to game inis to use memory card 251 for games that cannot use large memory cards
Move UDSPControl structure into DSP.h .
Move mixer construction to AudioCommon.cpp.
Delete AudioCommon::UseJIT().
Move audio handling out of DSP emulation.

This is good for a couple of reasons: one, it gets rid of duplicated code,
and two, DSP emulation shouldn't need to interact with audio in the first
place.
SW backend: make shaders work on Intel/Windows.

Apparently the Intel shader compiler doesn't implement "#if" correctly...
so use "#ifdef" instead.
Don't cast -1 to enum to represent a missing value.

This is undefined behavior in C++, and a clang warning suggests it is
actually producing bad code as a result:

../Source/Core/VideoCommon/BPFunctions.cpp:164:45: warning: comparison of constant 4294967295 with expression of type 'PEControl::PixelFormat' is always false [-Wtautological-constant-out-of-range-compare]
        if (new_format == old_format || old_format == (unsigned int)-1)
Fix harmless warnings.
