Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).
There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.

fixing things, partly by ignoring CPU models
that don't currently compile.
SConscript:
Split sources for fast, simple, and o3 CPU models into
separate source lists. For now none of these are included
in the base source list, so you won't get any CPU models
at all... but we still can't compile the other stuff so
it's not an issue.
Also get rid of obsolete encumbered/mem file.
