  Log Message:
  -----------
  [FunctionAttrs] Remove dead code code in nocaptures inference (NFCI)

An argument graph node without uses forms a trivial SCC, which will
already be handled by the preceding branch.

If a node in the SCC points to a node with empty uses, then it will
be part of a different SCC, and as such assumed to be capturing
if it does not have an attribute. There is no need to handle them
separately.
