PPC: [interpreter] Fix return address when entering exception handler.

Port ca51c204e1ab1519e2c623a74fad117577c37732

Original commit message:
    This fixes the broken return address when the exception handler within
    interpreted bytecode is being entered via stack unwinding. The address
    in question will never actually be taken, but our stack walker uses this
    address to determine whether a frame is interpreted.
