<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang-codegen Author: mikit (m1kit) <details> <summary>Changes</summary> It is undefined behavior to use `delete` expression on something which was not created with corresponding `new` expression. Switching to explicit global `operator delete()` call to match with `operator new()` call at `CGFunctionInfo::create()`.
