ipa-cp: Add dumping of overall_size after cloning

When experimenting with IPA-CP parameters, especially when looking
into exchange2_r, it has been very useful to know what the value of
overall_size is at different stages of the decision process.  This
patch therefore adds it to the generated dumps.

gcc/ChangeLog:

2020-09-07  Martin Jambor  <mjambor@suse.cz>

	* ipa-cp.c (estimate_local_effects): Add overeall_size to dumped
	string.
	(decide_about_value): Add dumping new overall_size.
