Message:

VMM/IEM: Working on BODY_CHECK_PC_AFTER_BRANCH and sideeffects of it. Fixed bug in 8-bit register stores (AMD64). Fixed bug in iemNativeEmitBltInCheckOpcodes (AMD64). Added a way to inject state logging between each instruction, currently only really implemented for AMD64. Relaxed the heave flushing code, no need to set the buffer pointer to NULL. Started looking at avoiding code TLB flushing when allocating memory to replace zero pages. bugref:10371
