This fixes a bug introduced by r28826 (Unify decoding of deoptimization translations, https://codereview.chromium.org/1136223004), where we started leaking arguments marker sentinel to the debugger, which would then cause crashes. This change replaces the sentinel with the undefined value in the debugger-inspectable frame.
