Zalathar 527c629cd9 coverage: Explicitly simplify coverage expressions in codegen ... After coverage instrumentation and MIR transformations, we can sometimes end up with coverage expressions that always have a value of zero. Any expression operand that refers to an always-zero expression can be replaced with a literal `Operand::Zero`, making the emitted coverage mapping data smaller and simpler. This simplification step is mostly redundant with the simplifications performed inline in `expressions_with_regions`, except that it does a slightly more thorough job in some cases (because it checks for always-zero expressions *after* other simplifications). However, adding this simplification step will then let us greatly simplify that code, without affecting the quality of the emitted coverage maps.		2023-09-21 18:32:49 +10:00
