Track if a physical page has been previously mapped executable. If it
has not been previously mapped EXE, flush it. If a writeable mapping
which is not executable occurs for the page, clear this bit.
Solves a problem where an executable page is double mapped, first without
EXE then accessed for execute at a different physical page, the cache
will behave properly.
