I noticed recently that the code is often used unsafe casting void* -> 
size_t and size_t -> void*. For example:

     const char *aligned_end = (const char *) ((size_t) end & 
~LONG_PTR_MASK);

I defer this issue until issues 14624 and 14624 will be resolved (same 
method is used in the suggested patches), but once it already mentioned, 
should be replaced size_t to Py_uintptr_t in all such castings?
