fbc93c0166 Lint against needless uses of collect()
Handles cases of `.collect().len()`, `.collect().is_empty()`, and
`.collect().contains()`. This lint is intended to be generic enough to
be added to at a later time with other similar patterns that could be
optimized.

Closes #3034

779988303a iter conservation efforts: save the endangered .iter() and .into_iter()
Make explicit_iter_loop and explicit_into_iter_loop allow-by-default, so
that people can turn them on if they want to enforce that style; avoid
presenting them as *the* idiomatic Rust style, rather than just *a* style.

81821acd59 Implement lint that checks for unidiomatic unwrap() (fixes #1770)
This checks for things like

    if x.is_some() {
        x.unwrap()
    }

which should be written using `if let` or `match` instead.

In the process I moved some logic to determine which variables are
mutated in an expression to utils/usage.rs.

5379fc1b28 better parsing of condition in while loop for mutability
allow condition to be a block: by calling visit_expr of the visitor directly on the condition instead of walk_expr on the whole expression, we bypass the match to ExprWhile that calls visit_expr on the condition and visit_block on the body. This allow to re-enable visit_block in the visitor, as it won't be called on the while body
allow condition to use static variables: maintain a list of static variables used, and if they are mutable

88aa04dfa5 don't lint while_let_on_iterator on nested loops
The problem is with a nested loop, the iterator may well be reused. This
changeset introduces a false negative, when the iterator is initialized
within the outer loop. A further PR could get rid of this false negative
by checking if the iterator is indeed initialized within the outer loop.
