accel/tcg: Move breakpoint recognition outside translation
Trigger breakpoints before beginning translation of a TB that would begin with a BP. Thus we never generate code for the BP at all. Single-step instructions within a page containing a BP so that we are sure to check each insn for the BP as above. We no longer need to flush any TBs when changing BPs.
