Ignore VectorType GetElementPtrInst (issues #29, #33)
code that I've been using to narrow down a miscompilation, that I believe will
be useful in the future

it has three parts
- build compiler-rt so that we can use UBSan from our LLVM version
- detailed srcloc printing for replaced instructions
- two command line options supporting binary search for a bogus
  transformation
Include hiredis via path "hiredis.h"

This seems to be more standard. For example, this is what the examples do.

Added instructions to isCommutative() function that were missed in UB patch
Merge pull request #45 from jubitaneja/additions-to-UB

Added instructions to isCommutative() function that were missed in UB pa...
Add the ability to use a function name instead of a instruction as an origin

This could be useful for serializing/deserializing a set of candidates.

Eventually CandidateMap will go away which should hopefully make it simpler
to drop this IR dependency.

add support for profiling Souper optimizations by incrementing a Redis variable
by the number times each optimized location executes
