These updates allow us to specify multiple testnames for `TESTNAME`.
The new version of compiletest-rs also includes `bless` support, but is
not enabled with this PR.

This renames the variants in HIR UnOp from
enum UnOp {
UnDeref,
UnNot,
UnNeg,
}
to
enum UnOp {
Deref,
Not,
Neg,
}
Motivations:
- This is more consistent with the rest of the code base where most enum
variants don't have a prefix.
- These variants are never used without the `UnOp` prefix so the extra
`Un` prefix doesn't help with readability. E.g. we don't have any
`UnDeref`s in the code, we only have `UnOp::UnDeref`.
- MIR `UnOp` type variants don't have a prefix so this is more
consistent with MIR types.
- "un" prefix reads like "inverse" or "reverse", so as a beginner in
rustc code base when I see "UnDeref" what comes to my mind is
something like "&*" instead of just "*".
disallowed_methods: Support functions in addition to methods
## Context:
Hey all! I have a particular use case where I'd like to ban certain functions in a code base I work on. For example, I want to ban `Instant::now()` (among others) as we have a time service for mocking time in deterministic simulation tests. Obviously, it doesn't make sense to include a lint like this for all clippy users. Imagine my excitement when I spotted the new `disallowed_methods` lint in clippy--perfect! Unfortunately, after playing around with it for a bit, I was frustrated to realize that it didn't support functions like `Instant::now()`, so I've added support for them in this PR.
It might also make sense to rename the lint from `disallowed_methods` -> `disallowed_functions`, though I've held off from including that rename in this change, since I'm unsure of clippy's breaking change policy.
## Change
Support functions in addition to methods. In other words, support:
`disallowed_methods = ["alloc::vec::Vec::new"]` (a function) in addition to
`disallowed_methods = ["alloc::vec::Vec::leak"]` (a method).
Improve the documentation to clarify that users must specify the full qualified path for each disallowed function, which can be confusing for reexports. Include an example `clippy.toml`.
Simplify the actual lint pass so we can reuse `utils::fn_def_id`.

This commit adds a new lint named filter_map_identity.
This lint is the same as `flat_map_identity` except that it checks for the usage of `filter_map`.
