History
Jakob Stoklund Olesen 990ca5517f Fix a quadratic algorithm in MachineBranchProbabilityInfo. 
The getSumForBlock function was quadratic in the number of successors
because getSuccWeight would perform a linear search for an already known
iterator.

This patch was originally committed as r161460, but reverted again
because of assertion failures. Now that duplicate Machine CFG edges have
been eliminated, this works properly.
