* Enables a few fixes for SN64's assembler related to div/divu instructions
*
* - SN64's assembler doesn't like assembling `div $0, a, b` with .set noat active.
* Removing the $0 fixes this issue (but not for handwritten asm)
*
* - SN64's assembler expands div to have break if dividing by zero
* However, the break it generates is different than the one it generates with `break N`
* So we replace break instrutions for SN64 with the exact word that the assembler generates when expanding div
