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.

Add uc_ctl_get/set_tcg_buffer_size 
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

Generate check_exit_request for the first tb 
Consider this case:

   t:inc ecx,
     inc edx,
     jmp t

It would generate exactly one block and TB chain will generate an inline
jump. If we don't check exit at the entry of the block, we will never be
terminated.

This test case is recorded in the commit message since it's a bit
painful to write multithread related code that builds on all platforms.
