Use `std::regex` as the backing implementation of `RegularExpression`.

This provides common and expected regex features, from basic features like
`\w` and `\d` character classes, to more advanced features such as lookahead.

This change used to be gated on the minimum GCC version, because some versions
of GCC had incomplete support for `std::regex`, but the GCC required by llvm
for the past couple years should be sufficient, according to docs. At this time
GCC >=7.1 is required.
