Get rid of baseBlock.  Now, when generated code is running, the guest
state pointer points directly at the ThreadState.arch.vex field, thus
updating it in place and avoiding a lot of code (and time-wasting)
which copies stuff back and forth to baseBlock.

Fix zillions of other places in the system where the current thread id
is needed.  It is now passed to all needed places.
