Add new `function_casts_as_integer` lint
The function_casts_as_integer lint detects cases where users cast a function pointer into an integer.
warn-by-default
Example
fn foo() {}
let x = foo as usize;
warning: casting a function into an integer implicitly
--> $DIR/function_casts_as_integer.rs:9:17
|
LL | let x = foo as usize;
| ^^^^^^^^
|
help: add `fn() as usize`
|
LL | let x = foo as fn() as usize;
| +++++++
Explanation
You should never cast a function directly into an integer but go through a cast as fn first to make it obvious what's going on. It also allows to prevent confusion with (associated) constants.

error: failed to test example in lint docs for `function_casts_as_integer` in /checkout/compiler/rustc_lint/src/function_cast_as_integer.rs:9: lint docs should start with the text "The `function_casts_as_integer` lint" to introduce the lint
This error was generated by the lint-docs tool.
This tool extracts documentation for lints from the source code and places
them in the rustc book. See the declare_lint! documentation
https://doc.rust-lang.org/nightly/nightly-rustc/rustc_lint_defs/macro.declare_lint.html
for an example of the format of documentation this tool expects.
To re-run these tests, run: ./x.py test --keep-stage=0 src/tools/lint-docs
The --keep-stage flag should be used if you have already built the compiler
and are only modifying the doc comments to avoid rebuilding the compiler.
Command has failed. Rerun with -v to see more details.

Applied suggestions. About enum variants: they have been updated, so now casting unit-line variants into integers is completely ok, and other variants casting into integer throw an error. So all good there. :)
