The size_info of ipa_size_summary are created by r277424. It should be
duplicated for cloned nodes, otherwise self_size and estimated_self_stack_size
would be 0, causing param large-function-insns and large-function-growth working
inaccurate when ipa-inline.
gcc/ChangeLog:
2019-12-18 Luo Xiong Hu <[email protected]>
* ipa-fnsummary.c (ipa_fn_summary_t::duplicate): Copy
ipa_size_summary for cloned nodes.
