tcg: move locking for tb_invalidate_phys_page_range up
In the linux-user case all things that involve ''l1_map' and PageDesc
tweaks are protected by the memory lock (mmpa_lock). For SoftMMU mode
we previously relied on single threaded behaviour, with MTTCG we now use
the tb_lock().
As a result we need to do a little re-factoring and push the taking of
this lock up the call tree. This requires a slightly different entry for
the SoftMMU and user-mode cases from tb_invalidate_phys_range.
This also means user-mode breakpoint insertion needs to take two locks
but it hadn't taken any previously so this is an improvement.
