a5c5645bed DSPIntMultiplier: Place translation unit local functions in an anonymous namespace 
Unlike inline, this makes the functions internally linked.

1020a3cb8e DSP/Jit: Explicitly specify scratch register for Update_SR_Register 
There were cases when the value register was RDX and thus was being
clobbered as RDX was implictly used as a scratch register.

26e9c54886 DSPEmitter: Make helper functions private 
Given none of these are used outside of the DSPEmitter class (nor does
it really make sense to allow them to be used outside of the class),
these should all be made private.

552c0d8404 Common: Move byte swapping utilities into their own header 
This moves all the byte swapping utilities into a header named Swap.h.

A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.

Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.

10d73988e7 DSPCore: Convert DSP stack register enum into an enum class 
Makes it more self-documenting which stack is being loaded or stored to,
as C, D, and magic numbers are extremely vague. It also enforces a
strongly-typed API instead of accepting arbitrary integral values.

It also adds the two other missing stack register names -- loop address
and loop counter.

970d969f63 DSPEmitter: Make conditional JIT functions in DSPJitBranch part of the emitter 
These quite clearly have a dependency on the emitter itself, so these
should be a part of the emitter itself.

The template function can be modified to just simply take functions as a
parameter.

cbe1ec51df DSPAssembler: Make AssembleFile take a std::string 
File paths passed to it would have been implicitly converted to std::strings
prior to this function being reached, so it gets rid of some string churn.
It also makes it safer since nullptr can't be passed in.

35cc4a4202 DSPInterpreter: Get rid of a #define constant 
This constant isn't particularly helpful, mainly because it's not
applicable to all DSP instructions. Some instructions don't have encoding
space for registers, and not all instructions that do encode registers
have one at the first five bits.

This change also has the benefit of removing all includes to the
interpreter within the JIT code, which keeps them fully separate from one
another. Changes to the interpreter header won't require some of the JIT
code to be rebuilt.
