Pokechu22 464575702b DSPSpy: Replace less_test with cond_test
This new test covers all conditions, and also tests overflow, carry, logical zero, and the behavior of NEG

Pokechu22 f9e36bfa67 DSPLLE: Split SRS into SRS and SRSH
Hardware testing indicated that SRS uses a different list of registers than LRS (specifically, acS.h can be used with SRSH but not LRS, and SRS does not support AX registers, and there are 2 encodings that do nothing).

Pokechu22 51c26d82a5 DSPSpy: Require user to specify a test_main label
This makes the point where execution starts more obvious compared to a start_of_test label at the end of the include, and allows putting other functions at the start of the file.  This change also modifies the existing tests to build with this change.

Pokechu22 5f7c852d22 DSPSpy: Split main dsp_base logic from interrupt handlers
This is so that interrupt handlers can be manually specified in tests that need them.

Pokechu22 1ad8dd7634 DSPSpy: Remove build.sh and sbuild.sh
This also removes the emu folder from the Makefile, and the Config.h file.  I'm not entirely sure what build.sh was for, but my best guess is that it was some kind of tool to run emulated DSP code at the same time as the actual DSP code and compare the results.  I don't know if it ever worked, but it certainly doesn't work now.

Pokechu22 14119c86a4 DSPInterpreter: Fix IsLess
`IsLess` would incorrectly return true if both `SR_OVERFLOW` and `SR_SIGN` are set, as `(sr & SR_OVERFLOW) != (sr & SR_SIGN)` becomes `SR_OVERFLOW != SR_SIGN` which is true as the two masks are different.  This broke in e651592ef5.

This issue only affected the DSP LLE Interpreter, and not the DSP LLE JIT.

I've also included a simple test case for this.  `ax0.l` (on the top left) is set to 0 if the instruction following `IFL` does not execute and to 1 if it is executed.

Léo Lam 7c01127ac6 DSPSpy: Add a test for accelerator loop
This adds a test ucode that can be used to check the accelerator loop
behaviour with various start/end addresses.

It's actually more of a test template than a ready to use test.

Léo Lam e569d3bc4a DSPSpy/Base: Handle ACCOV exceptions
This allows dspspy to show that an ACCOV happened, and to resume
accelerator reads after an ACCOV (by refreshing the YN2 register).
