    [web snapshot] Support RegExp · add69092
    Vicky Kontoura authored
    This CL adds support for regular expressions. To serialize a regular
    expression, the pattern and flags are extracted and serialized as
    strings.
    
    Also, JSRegExp::StringFromFlags() is introduced to allow for
    transforming back from JSRegExp::Flags to the corresponding flag string.
    To verify that this implementation is on par with
    RegExp.prototype.flags, unittests are introduced under
    regexp/regexp-unittest.cc and RegExpBuiltinsAssembler::FlagsGetter()
    is updated to include a slow path that calls JSRegExp::StringFromFlags()
    through a runtime function.
