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.
