5d6e68454e Don't shrink live ranges after dead code elimination unless it is going to help. 
In particular, don't repeatedly recompute the PIC base live range after rematerialization.

62d49461b6 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.)

b9b420d588 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.

d3b1c5df33 PR9604; try to deal with RAUW updates correctly in the AST. I'm not convinced 
it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

9308e08aad fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which 
is substantially different than a(b|c)d.  Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

5add6d16b7 Build the Hopfield network incrementally when splitting global live ranges. 
It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

0c1aa958e2 Redirected errors from the AsmParser to the proper
