cap frequency in make_forwarder_block
In the testcase the block with problematic frequency has to incoming
edges. Each edge has probability 1. The first edge's source bb has
frequency 873/10000, and the second has a frequency of 9409/10000. So
at least one of those is slightly high probably from some sort of rounding
issue related to fixed point, but in any case make_forwarder_block
should not create basic blocks with frequency greater than BB_FREQ_MAX.
