Detailed Description
Data stored for each basic block.

| bitmap bb_data::backup |
Referenced by add_label_notes(), and find_occr_in_bb().
| bitmap bb_data::live_in |

process. BACKUP is used to record live_in info before trying to
hoist an expression, and will be used to restore LIVE_IN if the
expression should not be hoisted.

(defined only for the pressure classes).
Referenced by add_label_notes(), and find_occr_in_bb().
| int bb_data::old_pressure |
Recorded register pressure of basic block before trying to hoist
an expression. Will be used to restore the register pressure
if the expression should not be hoisted.
