    Revert of [Interpreter] Adds support to fetch return value on break at return. (patchset #9 id:160001 of https://codereview.chromium.org/1818873003/ )
    
    Reason for revert:
    [Sheriff] Seems to break nosnap debug:
    https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20nosnap%20-%20debug/builds/6019
    
    Original issue's description:
    > [Interpreter] Adds support to fetch return value on break at return.
    >
    > Debugger fetches the return value of a function when we break at return.
    > Interpreter holds the return value in accumulator. This is not stored in a
    > specified location on stack and hence it is not possible to look it up from
    > stack similar to full-codegen or optimized frames. This cl adds support to
    > store the value of accumulator on debug breaks. The value of accumulator is
    > passed to the runtime function and is then stored in thread local data.
    >
    > Also changes full-codegen implementation to match that of ignition.
    > The return value from full-codegen is also stored in thread local data.
    > The return value is fetched directly thread local data instead of
    > finding it by iterating over frames.
