    Scanner: disallow unicode escapes in regexp flags. · 2b026851
    marja@chromium.org authored
    The spec explicitly forbids them. V8 never handled them properly either, just
    the Scanner accepted them (it had code to add them literally to the
    LiteralBuffer) and later on, Regexp constructor disallowed them.
    
    According to the spec, unicode escapes in regexp flags should be an early error
    ("It is a Syntax Error if IdentifierPart contains a Unicode escape sequence.").
    
    Note that Scanner is still more relaxed about regexp flags than the
    spec. Especially, it accepts any identifier parts (not just a small set of
    letters) and doesn't check for duplicates.
