This implements support for named captures in
RegExp.prototype[@@replace] for when the replaceValue is not callable.
Named captures can be referenced from replacement strings by using the
"$<name>" syntax. A couple of examples:
let re = /(?<fst>.)(?<snd>.)/u;
"abcd".replace(re, "$<snd>$<fst>") // "bacd"
"abcd".replace(re, "$2$1") // "bacd" (numbered refs work as always)
"abcd".replace(re, "$<snd") // SyntaxError (unterminated named ref)
"abcd".replace(re, "$<42$1>") // "cd" (invalid name)
"abcd".replace(re, "$<thd>") // "cd" (non-existent name)
"abcd".replace(/(?<fst>.)|(?<snd>.)/u, "$<snd>") // "cd" (non-matched capture)
Support is currently behind the --harmony-regexp-named-captures flag.
