CIE - Common Information Element

There is one per function, and it describes where the function code
is located, and what the register lifetimes and stack layout are
within the function.
The data structures are defined in the DWARF specfication, although
not in a very readable way (see LITERATURE).
Every time an exception is thrown, the code needs to locate the FDE
for the current function, and starts to look for exception regions
from that FDE. This works in a two-level search:
a) in a linear search, find the shared image (i.e. DLL) containing
the PC
b) using the FDE table for that shared object, locate the FDE using
binary search (which requires the sorting). */
