Timothy Flynn f1dd770a8a LibJS: Parse RegExp literals at AST creation time, not execution time 
The spec requires that invalid RegExp literals must cause a Syntax Error
before the JavaScript is executed. See:
https://tc39.es/ecma262/#sec-patterns-static-semantics-early-errors

This is explicitly tested in the RegExp/property-escapes test262 tests.
For example, see unsupported-property-Line_Break.js:

    $DONOTEVALUATE();
    /\p{Line_Break}/u;

That RegExp literal is invalid because Line_Break is not a supported
Unicode property. $DONOTEVALUATE() just throws an exception when it is
executed. The test expects that this file will fail to be parsed.

Note that RegExp patterns can still be parsed at execution time by way
of "new RegExp(...)".
