Don't do DCE inside the pass, let the DCE pass actually handle this. This was causing later passes to crash

The BFI cascades in this particular instruction weren't optimal. Biggest improvement is the 8-bit version, while the 16-bit version gets a minor improvement. 8-bit instruction count reduced from 38 to 29. 16-bit instruction count reduced from 34 to 28. RCL can have a similar optimization done to it. ```asm Before 16-bit: 0x0000ffff80a801e0 10ffffe0 adr x0, #-0x4 (addr 0xffff80a801dc) 0x0000ffff80a801e4 f9005f80 str x0, [x28, FEX-Emu#184]
