9dbb018b36 Fix an issue in SimplifySetCC() specific to vector comparisons. 
When folding X == X we need to check getBooleanContents() to determine if the
result is a vector of ones or a vector of negative ones. 

I tried creating a test case, but the problem seems to only be exposed on a
much older version of clang (around r144500).

d5be48a9db Matrix simplification in PBQP may push infinite costs onto register options. 
The colorability heuristic should count these as denied registers.

No test case - this exposed a bug on an out-of-tree target.

a551a48402 Initial 64 bit direct object support. 
This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

aad9c3f17a Fast fix for PR12343: 
http://llvm.org/bugs/show_bug.cgi?id=12343

We have not trivial way for splitting edges that are goes from indirect branch. We can do it with some tricks, but it should be additionally discussed. And it is still dangerous due to difficulty of indirect branches controlling.

Fix forbids this case for unswitching.

8ba9405c5c Hack the hack. If we have a situation where an ASM object is defined but isn't 
reflected in the LLVM IR (as a declare or something), then treat it like a data
object.

N.B. This isn't 100% correct. The ASM parser should supply more information so
that we know what type of object it is, and what attributes it should have.
