+Subject: [PATCH] Fix AutocompleteMatch move constructor/assign operator noexcept
+
+For AutocompleteMatch to declare noexcept them, all the contained
+properties need to be noexcept too. This is required at least
+for SuggestionAnswer, because base::string16 will make default
+calculated signature of the move operator noexcept(false).
+
+To avoid this issue we explicitely declare them on SuggestionAnswer,
+and its member classes TextField and ImageLine.

+Subject: [PATCH] Avoid pure virtual crash destroying RenderProcessUserData
+
+When RenderProcessUserData is destroyed from the destructor of
+RenderProcessHostImpl, it is done in the destructor of RenderProcessHost.
+At this point RemoveObserver override is already freed, so RenderProcessHost
+is pure virtual. This crash happens at least building with GCC:
+
+    at /usr/include/c++/8/ext/new_allocator.h:140
+    (this=0x7fffffffcb50, __in_chrg=<optimized out>) at /usr/include/c++/8/bits/stl_tree.h:964
+
+We need to destroy RenderProcessUserData before that happens. To do that
+we can just override RenderProcessHostDestroyed.

+Subject: [PATCH] libstdc++: do not assume unique_ptr has ostream operator
+
+CompositorFrameReportingController is using DCHECK_NE to compare
+several unique_ptr. This is valid in libc++, but on libstdc++ unique_ptr
+does not have an ostream operator.
