const-prop: Restrict scalar pair propagation We now only propagate a scalar pair if the Rvalue is a tuple with two scalars. This for example avoids propagating a (u8, u8) value when Rvalue has type `((), u8, u8)` (see the regression test). While this is a correct thing to do, implementation is tricky and will be done later. Fixes #66971 Fixes #66339 Fixes #67019 2019-12-05 01:40:24 -06:00
