Merging r142491:
------------------------------------------------------------------------
r142491 | chandlerc | 2011-10-19 03:12:41 -0700 (Wed, 19 Oct 2011) | 9 lines

Add pass printing support to BlockFrequencyInfo pass. The implementation
layer already had support for printing the results of this analysis, but
the wiring was missing.

Now that printing the analysis works, actually bring some of this
analysis, and the BranchProbabilityInfo analysis that it wraps, under
test! I'm planning on fixing some bugs and doing other work here, so
having a nice place to add regression tests and a way to observe the
results is really useful.
