Refactor translation block CPU state handling (Jan Kiszka)
This patch refactors the way the CPU state is handled that is associated
with a TB. The basic motivation is to move more arch specific code out
of generic files. Specifically the long #ifdef clutter in tb_find_fast()
has to be overcome in order to avoid duplicating it for the gdb
watchpoint fixes (patch "Restore pc on watchpoint hits").
