Set the temporary tablespace flag.
The latch order constraints are different for intrinsic tables. We don't always acquire the index->lock. We need to figure out the context and add some special rules during the checks.

Print the latch context.
Implemented in rw_lock_t, and MutexDebug< Mutex >::Context.
latch_id_t latch_t::m_id |
Latch ID.
bool latch_t::m_rw_lock |
true if it is a rw-lock.
In debug mode, rw_lock_t derives from this class and sets this variable.
bool latch_t::m_temp_fsp |
true if it is an temporary space latch
