[chkp] Clear instrumented_version and thunk_info in cgraph_node::reset

[Jan Hubicka]

Hi,
this patch makes the code turning instrumentation thunks into transparent
aliases to work.

Bootstrapped/regtested x86_64-linux, will commit it later today.

        * cgraphunit.c (cgraph_node::reset): Clear thunk info and
        instrumented_version, too.
