rustc/rustc_mir: Implement RFC 2203. This commit implements RFC 2203, allowing constants in array repeat expressions. Firstly, the check that the array repeat expression implements `Copy` is removed and re-implemented in `rustc_mir::borrow_check::nll::type_check` by emitting an error when the MIR contains a `Operand::Move` and the type does not implement `Copy`. Next, the `qualify_consts` pass is modified to construct a `Candidate::Repeat` when it would be correct to promote a array repeat expression. Finally, the `promote_consts` pass is modified to promote the candidates previously identified. 2019-05-26 11:57:00 +00:00			`\|`

rustc_mir: Re-use `report_selection_error`. This commit replaces the new error that was being emitted in NLL type check with a call to `report_selection_error` so that the same trait error as before this PR is emitted. 2019-06-12 07:26:16 +00:00			For more information about this error, try `rustc --explain E0277`.
