Some renamings: s/ast_ty/hir_ty and s/StructField/hir::StructField 
I think in both cases the new names make the code more understandable.
For `StructField` specifically because there's one in
[`syntax::ast`][ast] and one in [`rustc::hir`][hir].

[ast]: https://doc.rust-lang.org/nightly/nightly-rustc/syntax/ast/struct.StructField.html
[hir]: https://doc.rust-lang.org/nightly/nightly-rustc/rustc/hir/struct.StructField.html

3cf8c0b3b5 Fix cast_sign_loss false positive 
This checks if the value is a non-negative constant before linting about
losing the sign.

Because the `constant` function doesn't handle const functions, we check if
the value is from a call to a `max_value` function directly. A utility method
called `get_def_path` was added to make checking for the function paths
easier.

Fixes #2728

Add wildcard_match_arm lint

This lint prevents using a wildcard in a match arm. Implemented as a restriction currently, because this is pretty much an edge case. See #3649 for more information.

Didn't add any tests because I wasn't sure how, but if someone wants to point me in the right direction, I'd be happy to!

Update various docs 
* `const_transmute` currently also seems to depend on the `const_fn`
  feature.
* Only `Sized` is currently allowed as a bound, not Copy.

Prevent incorrect cast_lossless suggestion in const_fn

`::from` is not a const fn, so applying the suggestion of
`cast_lossless` would fail to compile. The fix is to skip the lint if
the cast is found inside a const fn.
