Given that we now have a tree that compiles fine against
-Werror=mismatched-dealloc, we need to make sure that we don't regress.
By adding the malloc attribute[0], we can protect against regressions,
enable more accurate code coverage with -fanalyzer, and allow the
compiler to do some optimizations.
Let me know if I missed any allocators. Additionally, does it make sense
to add the attribute to the various memory context allocator functions
like AllocSetAlloc(), or only on the higher level functions.
