  1. coll: add a new bcast composition 

    Add composition delta for bcast that can utilize the direct links between
the GPUs in the same node. This composition delta is basically the same as
composition alpha, it just moves the data swap before the intra-node bcast.

  2. coll: improve readability in MPIDI_Bcast_intra_composition_alpha 

    When the root is not the local node leader, the data needs to be sent
from the root to the local leader. Rewrite that part of code to make
it more clear.
