[PATCH v2 00/10] tcg: breakpoint reorg

[Richard Henderson]

This is fixing #404 ("windows xp boot takes much longer...")
and several other similar reports.

For v2, all prerequisites and 7 of the patches from v1 with
reviews are now upstream.

Mark Cave-Ayland reported success with WinXP with v1, with
this patch set being even faster than b55f54bc~1.  Which was
a bit of a surprise, but I'll take it.  It means that it's
probably not worth making the breakpoint detection scheme
any more complicated.

I'd still like some more feedback.  Given this is fixing a
regression from qemu 5.2 I feel comfortable delaying this
past soft freeze, but not past hard freeze on the 20th.
