Remove old and redundant options

We remove -polly-detect-unprofitable and -polly-no-early-exit. Both have been
superseeded by -polly-process-unprofitable and were only kept as aliases for
our buildbots to continue to work. As all buildbots have been moved to the new
options, we can now remove the old ones for good.
