[deoptimizer] Do not pass arguments markers to the debugger.

[deoptimizer] Do not pass arguments markers to the debugger.

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.

Could take a look, please?

It turns out the arguments object screw-up was caused by my deoptimizer
refactoring.
