  Log Message:
  -----------
  [MCA][InstrBuilder] Always check for implicit uses of resource units (PR50725).

When instructions are issued to the underlying pipeline resources, the
mca::ResourceManager should also check for the presence of extra uses induced by
the explicit consumption of multiple partially overlapping group resources.

Fixes PR50725
