Rollup merge of #69784 - benesch:fast-strip-prefix-suffix, r=kennytm
Optimize strip_prefix and strip_suffix with str patterns As mentioned in https://github.com/rust-lang/rust/issues/67302#issuecomment-585639226. I'm not sure whether adding these methods to `Pattern` is desirable—but they have default implementations so the change is backwards compatible. Plus it seems like they're slated for wholesale replacement soon anyway? #56345 ---- Constructing a Searcher in strip_prefix and strip_suffix is unnecessarily slow when the pattern is a fixed-length string. Add strip_prefix and strip_suffix methods to the Pattern trait, and add optimized implementations of these methods in the str implementation. The old implementation is retained as the default for these methods.
