rust-regex: fix issues with regex anchoring and performance...

rust-regex: fix issues with regex anchoring and performance It turns out that the way I tried to work around `regex`'s behavior difference with `re2` and Python's `re` was 1) buggy and 2) much more complicated than needed. In a few words: `regex` adds `.*` on either side of patterns when no start or end anchor is present. My previous workaround put `^` or `$` for every pattern, which is wrong even without the other 2 bugs on top of it. Using `^(?:<patterns>)` right at the end of the `regex` path fixes the issue. I've opened an issue to get a build option instead: https://github.com/rust-lang/regex/issues/675 Differential Revision: https://phab.mercurial-scm.org/D8506
