dac5dbadeb Fix reassociate to use a worklist instead of recursing when new 
reassociation opportunities are exposed. This fixes a bug where
the nested reassociation expects to be the IR to be consistent,
but it isn't, because the outer reassociation has disconnected
some of the operands.  rdar://9167457

d7bb295d22 Beginning of the Great Exception Handling Rewrite. 
* Add a "landing pad" attribute to the BasicBlock.
* Modify the bitcode reader and writer to handle said attribute.

Later: The verifier will ensure that the landing pad attribute is used in the
appropriate manner. I.e., not applied to the entry block, and applied only to
basic blocks that are branched to via a `dispatch' instruction.

(This is a work-in-progress.)

15f8951799 fix rdar://8735979 - "int 3" doesn't match to "int3". Unfortunately, 
InstAlias doesn't allow matching immediate operands, so we have to write
C++ code to do this.

If lower bound and upper bound are zero than array has one element.
