Drop partially bound function parameters in the expected order
Given the function
```rust
fn foo((_x, _): (LogDrop, LogDrop), (_, _y): (LogDrop, LogDrop)) {}
```
Prior to 1.12.0 we dropped both `_x` and `_y` before the rest of their
respective parameters, since then we dropped `_x` and `_y` after. The
original order appears to be the correct order, as the value created
later is dropped first, so we revert to that order and add a test for
it.
While this is technically a breaking change, I can't work out how
anyone could be relying on this without making their code very
brittle. If this is considered to be too likely to break real world code
then I can revert the change and change the test to check for the
current order.
Use structured suggestions for nonstandard style lints
This PR modifies the lints in the nonstandard_style group to use structured suggestions. Note that there's a bit of tricky span calculation going on for the `crate_name` attribute. It also simplifies the code a bit: I don't think the "fallback" suggestions for these lints can actually be triggered.
