Various changes needed to get Addrcheck supported:
* Rearrange iropt pipeline so that tree-building is
no longer anything to do with optimisation, but is
instead done post-instrumentation
* Allow two instrumentation functions to be passed to
LibVEX_Translate, not one, so that valgrind can also
do an sp-update pass
* Add a type VexGuestLayoutInfo for describing the guest
state, for the benefit of instrumenters.
