Remove code duplication from the dispatchers. Keep the core loop
in common.
To accomplish that without penalizing the non-profiling dispatcher
we do the stats gathering *after* the jitted code returns to the
dispatcher. For that to work properly, we need to stash away the
instruction adddress before entering the jitted code so we can use
it later. (See also VEX r2208).
Two other tweaks are included here:
(1) For the non-profiling dispatcher it is not necessary to update
the LR in each iteration. Quite obviously the jitted code cannot
modify the LR in its iteration because it needs it at the very end
when it returns. So we move this step out of the core loop.
(2) Move loading the address of VG_(tt_fast) past testing for a changed
guest state pointer.
