[mir-opt] Turn on the `ConstProp` pass by default
perf.rlo shows that running the `ConstProp` pass results in across-the-board wins regardless of debug or opt complilation mode. As a result, we're turning it on to get the compile time benefits. `ConstProp` doesn't currently intern the memory used by its `Machine` so we can't yet propagate allocations which is why `ConstProp::should_const_prop()` checks if the value being propagated is a scalar or not.
