2020-09-29	Say "doesn't" instead of "wouldn't" in convert message	Camelid	-132/+132

2020-09-29	Add article after "to"	Camelid	-227/+227
	Also added missing backtick in "you can cast" message.
2020-09-27	Use correct article in help message for conversion or cast	Camelid	-119/+119
	Before it always used `an`; now it uses the correct article for the type.

2020-06-13	Note numeric literals that can never fit in an expected type	Ayaz Hafiz	-0/+96
	re https://github.com/rust-lang/rust/pull/72380#discussion_r438289385 Given the toy code ```rust fn is_positive(n: usize) { n > -1_isize; } ``` We currently get a type mismatch error like the following: ``` error[E0308]: mismatched types --> src/main.rs:2:9 \| 2 \| n > -1_isize; \| ^^^^^^^^ expected `usize`, found `isize` \| help: you can convert an `isize` to `usize` and panic if the converted value wouldn't fit \| 2 \| n > (-1_isize).try_into().unwrap(); \| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ``` But clearly, `-1` can never fit into a `usize`, so the suggestion will always panic. A more useful message would tell the user that the value can never fit in the expected type: ``` error[E0308]: mismatched types --> test.rs:2:9 \| 2 \| n > -1_isize; \| ^^^^^^^^ expected `usize`, found `isize` \| note: `-1_isize` can never fit into `usize` --> test.rs:2:9 \| 2 \| n > -1_isize; \| ^^^^^^^^ ``` Which is what this commit implements. I only added this check for negative literals because - Currently we can only perform such a check for literals (constant value propagation is outside the scope of the typechecker at this point) - A lint error for out-of-range numeric literals is already emitted IMO it makes more sense to put this check in librustc_lint, but as far as I can tell the typecheck pass happens before the lint pass, so I've added it here. r? @estebank
2020-06-11	fixup! Provide suggestion to convert numeric op LHS rather than unwrapping RHS	Ayaz Hafiz	-138/+463

2020-06-11	Provide suggestion to convert numeric op LHS rather than unwrapping RHS	Ayaz Hafiz	-0/+1700
	Given a code ```rust fn foo(x: u8, y: u32) -> bool { x > y } fn main() {} ``` it could be more helpful to provide a suggestion to do "u32::from(x)" rather than "y.try_into().unwrap()", since the latter may panic. We do this by passing the LHS of a binary expression up the stack into the coercion checker. Closes #73145
2020-05-20	refactor check_for_cast	Bastian Kauschke	-0/+10

2020-04-28	Fix numeric-cast tests for new `into` suggestion	Samrat Man Singh	-63/+43
	Remove `integer-into.rs` since the numeric-cast tests already cover these cases.
