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 present and future qemu/tcg statisti

Adding -d tb_stats to control TBStatistics collection:

"dump_limit" is used to limit the number of dumped TBStats in
linux-user mode.
[all+jit+exec+time] control the profilling level used
by the TBStats. Can be used as follow:

If a TB has a TBS (TBStatistics) with the TB_EXEC_STATS
enabled, then we instrument the start code of this TB
to atomically count the number of times it is executed.
We count both the number of "normal" executions and atomic
executions of a TB.
The execution count of the TB is stored in its respec

We add some of the statistics collected in the TCGProfiler
into the TBStats, having the statistics not only for the whole
emulation but for each TB. Then, we removed these stats
from TCGProfiler and reconstruct the information for the
"info jit" using the sum of all TBStats statistics.
