Subject: [PATCH 1/2] tools/memory-model: clarify the origin/scope of the tool name

Ingo pointed out that:

  "The "memory model" name is overly generic, ambiguous and somewhat
   misleading, as we usually mean the virtual memory layout/model
   when we say "memory model". GCC too uses it in that sense [...]"

Make it clearer that, in the context of tools/memory-model/, the term
"memory-model" is used as shorthand for "memory consistency model" by
calling out this convention in tools/memory-model/README.

Stick to the full name in sources' headers and for the subsystem name.
