2020-10-01	Disable the SimplifyArmIdentity mir-opt	Wesley Wiser	-1/+1
	The optimization still has some bugs that need to be worked out such as #77359. We can try re-enabling this again after the known issues are resolved.
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.
