c43ea147bf ~1% emulation speedup by skipping pageWriteStamp check for stack writes. 
For now the optimization is supported only when no SMP is compiled in because it doesn't handle cross-modifying code.

The current stack page will cache also current pageWriteStamp for that page and could skip pageWriteStamp access if possible.
Any code fetch access missing trace cache will invalidate current stack page.
Code fetch accesses from another SMP threads should do the same to support SMP.

Next step:
 - support SMP
 - support pageWriteStamp access skipping for all other memory writes from all segments
