2019-11-21	Introduce MIR optimizations for simplifying `x?` on `Result`s.	Mazdak Farrokhzad	-0/+17
	This optimization depends on inlining for the identity conversions introduced by the lowering of the `?`. To take advantage of `SimplifyArmIdentity`, `-Z mir-opt-level=2` is required because that triggers the inlining MIR optimization.
