[v2,07/13] gdb: add frame_id::user_created_p
Commit Message
Later in this series, we'll need to differentiate frame ids for regular
frames (obtained from the target state and unwinding from it) vs frame
ids for user-created frames (created with create_new_frame). Add the
frame_id::user_created_p field to indicate a frame is user-created, and
set it in create_new_frame.
The field is otherwise not used yet, so not changes in behavior are
expected.
