Hi all,
I'd like to submit this patch.
It release the ipa cp transformation summary after functions being expanded.
This is to fix the compiler when used with libgccjit on subsequent
compilations (every new compilation should have a clean transformation
summary).
Bootstrap on arm64 and X86-64.
Bests

* cgraphunit.c (expand_all_functions): Release ipcp_transformation_sum
when finished.
* ipa-prop.c (ipcp_free_transformation_sum): New function.
* ipa-prop.h (ipcp_free_transformation_sum): Add declaration.
