PPC/s390: [builtins] New frame type for exits to C++ builtins

Browse Source 
Port 5febc27b5d

Original commit message:

    Prior to this commit, calls to C++ builtins created standard exit
    frames, which are skipped when constructing JS stack traces. In order to
    show these calls on traces, we introduce a new builtin exit frame type.

    Builtin exit frames contain target and new.target on the stack and are
    not skipped during stack trace construction.
