Retry submitting r186623: COFFDumper: Dump data directory entries.

The original change was rolled back in r186627 because of test
failures on the big endian machine. I believe I fixed the issue
so re-submitting.

Refactor AnalyzeBranch on ARM. The previous version did not always analyze
indirect branches correctly. Under some circumstances, this led to the deletion
of basic blocks that were the destination of indirect branches. In that case it
left indirect branches to nowhere in the code.

This patch replaces, and is more general than either of the previous fixes for
indirect-branch-analysis issues, r181161 and r186461.

For other branches (not indirect) this refactor should have *almost* identical
behavior to the previous version. There are some corner cases where this
refactor is able to analyze blocks that the previous version could not (e.g.
this necessitated the update to thumb2-ifcvt2.ll).
