[Andreas Neustifter]

Hi,

this is the ninth (and last, for now) in a series of patches to cleanup and improve the LLVM Profiling Infrastructure. It depends on the previous patches from

This patch introduces the ProfileVerifier, a pass that calculates for each block if the sum of the incoming weights is equal to the weight of the block and equal to the sum of the outgoing weights. It is not strictly necessary for profiling but it makes development of profiling related passes easier, thus its published also.
