commit 64b0cff3bee6b00cb4193ed887439c66055f85b4

    PR13714 - Make sure REG_STATE.cfa_is_expr is always set correctly.
    
    runtime/unwind.c (processCFI): Always set REG_STATE.cfa_is_expr and
    add new sanity checks to make sure the cfa definition rules are sane.
    
    Since the cfa expr pointer and cfa register/offset rule shared a union
    not setting REG_STATE.cfa_is_expr could result in compute_expr ()
    wrongly being called and using the register/offset as expr pointer.
