------- Comment #1 from ggaren at apple.com  2008-10-20 10:25 PDT -------
The problem is that CodeBlock::getStubInfo is N^2, and Gavin's recent change to
cache function calls caused much heavier reliance on it.

We should:

1. Change getStubInfo to use a hashtable, so it's no longer N^2
2. Stop using the structureIDInstructions vector to hold data other than
instructions whose StructureIDs need reference counting, so
structureIDInstructions returns to making sense.
