Handle non-trivial nil closures 
`reduce_nil_closure` mixed together a) 'is this a nil closure?' and b) 'can it
be reduced to a simple expression?'. Split the logic into two functions so we
can still generate a basic warning when the closure can't be simplified.

Fix useless_format false positive with macros 
Clippy was issuing a warning when `format!` was used inside a macro.
That's a problem because macros have different syntax and can be outside
the control of the user.

This skips the `useless_format` check if the `format!` call is inside a
macro.

Move empty_line_after_outer_attribute to nursery 
From the clippy side it's difficult to detect empty lines between
an attributes and the following item because empty lines and comments
are not part of the AST. The parsing currently works for basic cases
but is not perfect and can cause false positives.

Maybe libsyntax 2.0 will fix some of the problems around attributes but
comments will probably be never part of the AST so we would still have
to do some manual parsing.

Fix false positive in empty_line_after_outer_attr 
Before, when you had a block comment between an attribute and the
following item like this:

```rust
\#[crate_type = "lib"]
/*

*/
pub struct Rust;
```

It would cause a false positive on the lint, because there is an empty
line inside the block comment.

This makes sure that basic block comments are detected and removed from
the snippet that was created before.

546d2fec29 Fix enum_glob_use false positives 
Closes #2397.

This checks the def of the `ItemUse` path instead of checking the
capitalization of the path segements. It was noted that this def would
sometimes be `Def::Mod` instead of `Def::Enum` but it seems correct now.

Fix false positive in empty_line_after_outer_attribute 
`empty_line_after_outer_attribute` produced a false positive warning when
deriving `Copy` and/or `Clone` for an item.

It looks like the second point in [this comment][that_comment] is related,
as the attribute that causes the false positive has a path of
`rustc_copy_clone_marker`.

Fixes #2475
