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.
