      Description

      For a C1-compiled method, at the beginning of Method::{_from_compiled_entry,_from_compiled_value_ro_entry}, we make a call to Runtime1::{buffer_value_args, buffer_value_args_no_receiver_id} to allocate the buffered objects for the parameters of inlined class types. When a GC happens in here, we need to scan the outgoing parameters of the caller frame, so that any objects parameters can be properly marked/relocated.
