Downgrade match_bool to pedantic

I don't quite buy the justification in https://rust-lang.github.io/rust-clippy/. The justification is:

> It makes the code less readable.

In the Rust codebases I've worked in, I have found people were comfortable using `match bool` (selectively) to make code more readable. For example, initializing struct fields is a place where the indentation of `match` can work better than the indentation of `if`:

```rust
let _ = Struct {
    v: {
        ...
    },
    w: match doing_w {
        true => ...,
        false => ...,
    },
    x: Nested {
        c: ...,
        b: ...,
        a: ...,
    },
    y: if doing_y {
        ...
    } else { // :(
        ...
    },
    z: ...,
};
```

Or sometimes people prefer something a bit less pithy than `if` when the meaning of the bool doesn't read off clearly from the condition:

```rust
if set.insert(...) {
    ... // ???
} else {
    ...
}

match set.insert(...) {
    // set.insert returns false if already present
    false => ...,
    true => ...,
}
```

Or `match` can be a better fit when the bool is playing the role more of a value than a branch condition:

```rust
impl ErrorCodes {
    pub fn from(b: bool) -> Self {
        match b {
            true => ErrorCodes::Yes,
            false => ErrorCodes::No,
        }
    }
}
```

And then there's plain old it's-1-line-shorter, which means we get 25% more content on a screen when stacking a sequence of conditions:

```rust
let old_noun = match old_binding.is_import() {
    true => "import",
    false => "definition",
};
let new_participle = match new_binding.is_import() {
    true => "imported",
    false => "defined",
};
```

Bottom line is I think this lint fits the bill better as a pedantic lint; I don't think linting on this by default is justified.

Fixes issue #4892.

First contribution here 😊 ! Do not hesitate to correct me.

This PR is related to issue #4892 .

# Summary

```rust
-literal.method_call(args)
```
The main idea is to not trigger `clippy::precedence` when the method call is an odd function.

# Example

```rust
// should trigger lint
let _ = -1.0_f64.abs() //precedence of method call abs() and neg ('-') is ambiguous

// should not trigger lint
let _ = -1.0_f64.sin() // sin is an odd function => -sin(x) = sin(-x)
```

# Theory

Rust allows following literals:
- char
- string
- integers
- floats
- byte
- bool

Only integers/floats implements the relevant `std::ops::Neg`.
Following odd functions are implemented on i[8-128] and/or f[32-64]:
- `asin`
- `asinh`
- `atan`
- `atanh`
- `cbrt`
- `fract`
- `round`
- `signum`
- `sin`
- `sinh`
- `tan`
- `tanh `
- `to_degrees`
- `to_radians`

# Implementation

As suggested by `flip1995` in [comment](https://github.com/rust-lang/rust-clippy/issues/4892#issuecomment-568249683), this PR add a whitelist of odd functions and compare method call to the the whitelist before triggering lint.

changelog: Don't trigger [`clippy::precedence`] on odd functions.
