Emilio G. Cota f19c6cc6fc translate-all: report correct avg host TB size
Since commit 6e3b2bfd6 ("tcg: allocate TB structs before the
corresponding translated code") we are not fully utilizing
code_gen_buffer for translated code, and therefore are
incorrectly reporting the amount of translated code as well as
the average host TB size. Address this by:

- Making the conscious choice of misreporting the total translated code;
  doing otherwise would mislead users into thinking "-tb-size" is not
  honoured.

- Expanding tb_tree_stats to accurately count the bytes of translated code on
  the host, and using this for reporting the average tb host size,
  as well as the expansion ratio.

In the future we might want to consider reporting the accurate numbers for
the total translated code, together with a "bookkeeping/overhead" field to
account for the TB structs.
