Regex literal syntax
This adds syntax for regex literals equivalent to the literal syntax in JavaScript. It is effectively just syntax sugar for the %re syntax extension, but opens up the additional possibility of checking the regex syntax during compilation.
The syntax looks like:
let re = /a.*c/mg
which is equivalent to:
let re = %re(`/a.*c/mg`)
and compiles to:
var re = /a.*c/mg;
Closes #6287
I think it might be worth adding an attribute to the expression not to incorrectly print escaped regexp as an unescaped one

I`m not sure I follow. Can you give an example?
Tests passing! :partying_face:
I'm sure the code quality could be improved, and we could add validation of the internal regex syntax either before or after merging this.
@cknitt I'll do one last pass over the next few days to see if there aren't any edge cases.

Ping @IwanKaramazow 🙂
@glennsl As @IwanKaramazow does not seem to be available for review: Good to go from your point of view?
Then I'll merge and we can always refine things in follow-up PRs if necessary.
