.. and refactor js-regexp.h.
- Hide the generic DataAt/SetDataAt accessors and replace them by
dedicated accessors. Use the common lower_case naming scheme for
these.
- Shuffle around definitions in js-regexp.h s.t. they are in a
meaningful order.
- Dedupe the source/flags accessors - these fields are stored both
on the instance and on the data array. We keep only accessors for
the instance. Previously, these were disambiguated through naming
oddities (e.g. Pattern() returned data->source).

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.
