introduce `{char, u8}::is_ascii_octdigit`
This feature adds two new APIs: `char::is_ascii_octdigit` and `u8::is_ascii_octdigit`, under the feature gate `is_ascii_octdigit`. These methods are shorthands for `char::is_digit(self, 8)` and `u8::is_digit(self, 8)`:
```rust
// core::char
impl char {
pub fn is_ascii_octdigit(self) -> bool;
}
// core::num
impl u8 {
pub fn is_ascii_octdigit(self) -> bool;
}
```
---
Couple of things I need help understanding:
- `const`ness: have I used the right attribute in this case?
- is there a way to run the tests for `core::char` alone, instead of `./x.py test library/core`?
