These commands allow the exploration of TBs generated by the TCG.
Understand which one hotter, with more guest/host instructions... and
examine their guest, host and IR code.
The goal of this command is to allow the dynamic exploration of TCG
behavior and code qua

To store statistics for each TB, we created a TBStatistics structure
which is linked with the TBs. TBStatistics can stay alive after
tb_flush and be relinked to a regenerated TB. So the statistics can
be accumulated even through flushes.
The goal is to have all pr
TBStats will be introduced to replace CONFIG_PROFILER totally, here
remove all CONFIG_PROFILER related stuffs first.

We keep track of translations but can only do so up until the
translation cache is flushed. At that point we really have no idea if
