Change the ExitBlocks list from being explicitly contained in the Loop
...
structure to being dynamically computed on demand. This makes updating
loop information MUCH easier.

Add statistics to the loop extractor. The loop extractor has successfully
...
extracted all 63 loops for Olden/bh without crashing and without
miscompiling the program!!!

Fix several bugs in the loop extractor. In particular, subloops were never

Split into two passes. Now there is the general loop extractor, usable on

the command line, and the single loop extractor, usable by bugpoint
