Generate a 6502 test from the 65816 version by substituting the 16-bit instructions with 8-bit no-ops. There's a lot of project edits and weird stuff in the test, so this was much easier than starting over. The 65816 variant is largely unchanged, though it could now be stripped down to the stack-offset instructions.
