DSPInterpreter: Get rid of a #define constant

Browse Source 
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.
