````
Makes clippy tests pass again.

Correctly reject `TraitCandidate` in all cases
Follow up to #69255, addresses #69629.
When `self.select_trait_candidate(trait_ref)` returned `Err(_)`, `result` wasn't being set to `NoMatch`, causing invalid methods to be selected.
Previously, attributes on 'if' expressions (e.g. #[attr] if true {})
were disallowed during parsing. This made it impossible for macros to
perform any custom handling of such attributes (e.g. stripping them
away), since a compilation error would be emitted before they ever had a
chance to run.
This PR permits attributes on 'if' expressions ('if-attrs' from here on).
Both built-in attributes (e.g. `#[allow]`, `#[cfg]`) are supported.
We still do *not* accept attributes on 'other parts' of an if-else
chain. That is, the following code snippet still fails to parse:
```rust
if true {} #[attr] else if false {} else #[attr] if false {} #[attr]
else {}
```
Changes:
````
Apply suggestions from code review
Simplify if_chain.
Move NumericLiteral to its own module.
Included binary and octal cases.
Resolve false positives for hex int cast.
Test for unnecessary_cast of hex int literal.

For all of the methods that pick off the first or last element, we can
use subslice patterns to implement them directly, rather than relying on
deeper indexing function calls. At a minimum, this means the generated
code will rely less on inlining for performance, but in some cases it
also optimizes better.
nightly: bootstrap from 1.42.0-beta.5 (4e1c5f0e9 2020-02-28)
This beta snapshot has the llvm miscompilation fix included and is bootstrapped from a stable version that also has it included.
