notdirty_write: fix store-related performance problems
...
Every store would always cause the tb_invalidate_phys_page_fast path to be invoked,
amounting to a 40x slowdown of stores compared to loads.
Change this code to only worry about TB invalidation for regions marked as
executable (i.e. emulated executable).
Even without uc_set_native_thunks, this change fixes most of the performance
issues seen with thunking to native calls.

We still need this API because the virtual memory address space of
32 bits os is only 4GB and we default need 1G per instance
