2020-06-15	[const-prop] Remove `ConstPropMode::NoPropagation`	Wesley Wiser	-5/+4
	This mode is unnecessary because it's always ok to evaluate the right-hand side of assignments even if the left-hand side should not have reads propagated.
2020-05-24	Clear MIR local type annotations after borrowck	Jonas Schievink	-1/+1

2020-05-11	Modify SimplifyArmIdentity so it can trigger on mir-opt-level=1	Wesley Wiser	-1/+30
	I also added test cases to make sure the optimization can fire on all of these cases: ```rust fn case_1(o: Option<u8>) -> Option<u8> { match o { Some(u) => Some(u), None => None, } } fn case2(r: Result<u8, i32>) -> Result<u8, i32> { match r { Ok(u) => Ok(u), Err(i) => Err(i), } } fn case3(r: Result<u8, i32>) -> Result<u8, i32> { let u = r?; Ok(u) } ``` Without MIR inlining, this still does not completely optimize away the `?` operator because the `Try::into_result()`, `From::from()` and `Try::from_error()` calls still exist. This does move us a bit closer to that goal though because: - We can now run the pass on mir-opt-level=1 - We no longer depend on the copy propagation pass running which is unlikely to stabilize anytime soon.
