Some callers of brw_constant_fold_instruction depend on the result being
a MOV of immediate when progress is made. Previously `MUL dst:D src0:D
1:D` would be converted to `MOV dst:D src0:D`. There was also no
handling for `MUL dst:D imm0:D imm1:D`.
This could cause problems if one of the immedate values was -1. The
existing code would convert this to a `MOV dst:D imm0:D` and set the
negate flag on src0. That is not correct.
v2: Fix the is_negative_one case handling of the non-negative-one
source. Add a comment explaining the assertion. Both suggested by Caio.
