[mips][regexp] Consolidate calls to jitted irregexp and regexp interpreter

Port 213504b9

Original Commit Message:

    The code fields in a JSRegExp object now either contain irregexp
    compiled code or a trampoline to the interpreter. This way the code
    can be executed without explicitly checking if the regexp shall be
    interpreted or executed natively.
    In case of interpreted regexp the generated bytecode is now stored in
    its own fields instead of the code fields for Latin1 and UC16
    respectively.
    The signatures of the jitted irregexp match and the regexp interpreter
    have been equalized.
