Log:
CodegenCleanup: Drop -load-combine pass

This pass is not enabled in the default tool chain and currently can run into an
infinite loop, due to other parts of LLVM generating incorrect IR
(http://llvm.org/PR27065) -- which is not executed and consequently does not
seem to disturb other passes.  As this pass is not really needed, we can just
drop it to get our build clean.

This fixes the timeout issues in MultiSource/Benchmarks/MiBench/consumer-jpeg
and MultiSource/Benchmarks/mediabench/jpeg/jpeg-6a/cjpeg for
-polly-position=before-vectorizer -polly-process-unprofitable.. Unfortunately,
we are still left with a miscompile in cjpeg.
