Debugger: Fixed issues with NES/SNES/PCE assemblers
...
-Labels defined within the assembler that were referred to before their definition did not work properly and ended up being assigned the wrong value (when the label's address wasn't a value between 0x100 and 0xFFFF) - this is fixed by running multiple passes until the resulting byte code stops changing.
-Fixed issues where e.g EOR $00, Y would be assembled as a 2-byte instruction, which is invalid.

SNES: Set internal palette address to 0 when outputting bg color (when no layers have visible pixels)

This fixes regressions in PGA Tour Golf and Mini Yonku Shining Scorpion. These games attempt to write to CGRAM during rendering, but at a time where the background color is being rendered, so the writes overwrite address 0 in CGRAM. Without this fix, the last non-transparent pixel's color address was being used, causing it to corrupt the wrong color in CGRAM (which caused the glitches)
