The clarification RFC says `T.buffer_decl creates a buffer alias if the
underlying data variable (.data field) overlaps with another buffer. ` And this
should be the unique way to create buffer aliases.
Currently I understand that means all accesses with the same buffer data
<b>must</b> be alias (irrelavant to dtype) and the word `alias` take the same
meaning across TIR and target codegen levels. If so (fix me), no compatible
C/C++ type based aliasing rules can be introduced. cc @kparzysz-quic
