Originally I was hoping to get my whole debugger patch series on the
track, but I'm still stuck with a bug in the x86 debug register support
(weird single step race, triggered by dr-usage). So let's start smaller
with a friction of that series.
These patches introduce a new single step mode that allows the emulator
to generate and execute only a single-instruction TB, but without
triggering a debug event afterwards. This is exploited by
tb_invalidate_phys_page[_range] and later on by the watchpoint subsystem
(patch to be posted). This should also allow to remove cflags
from TranslationBlock, as done by the third patch.
