- Add multiple parameter broadcasting support for BCast. This will allow it to be used in multiparameter broadcasting contexts. This is specifically for ternary ops, but will be used to make other samplers like ParameterizedTruncatedNormal broadcast.
- Add batch index methods for generating a list of batch indices when the input vectors are flattened. This is used to get broadcasting on flattened inputs (which is used in the RandomBinomial sampler).
- Shard on the number of outputs. This allows us to scale better to Tensor inputs.

where both shapes are the same by using much more straightforward
code to achieve the same ultimate initialization of the various
instance variables with simpler code.
Added benchmark for this to bcast_test.cc. Speeds up the same_shape
case by 65% (67 ns to 23 ns for a two-dimensional shape) without
any real effect on the different shape case.
