José Julián Espina 8a664f2f24 Make `JsString` conform to miri tests (#2412 ) This PR rewrites some patterns of the `JsString` implementation in order to pass all its miri tests. This can be verified by running: ```bash cargo +nightly miri test -p boa_engine string::tests -- --skip builtins --skip parser ``` Basically, we were doing two operations that were Undefined Behaviour per the [Stacked Borrows](https://github.com/rust-lang/unsafe-code-guidelines/blob/master/wip/stacked-borrows.md) model: - Casting `&JsString` to `&mut RawJsString` to `&[u16]`. The intermediate mutable borrow must not exist, or Miri considers this as Undefined Behaviour. - Trying to access `RawJsString.data` using the dot operator. Miri complains with `this is a zero-size retag ([0x10..0x10]) so the tag in question does not exist anywhere`. To fix this, we can recompute the position of `data` every time we want to access it.		2 years ago
