This expands NRVO propagation for more cases:

Parse analysis improvement:

  Lambdas and Blocks with dependent return type can have their variables marked as
  NRVO Candidates.

Variable instantiation improvement:

  Functions, Lambdas, and Blocks which have auto return type have their
  variables' NRVO status propagated. For Blocks with non-auto return type,
  as a limitation, this propagation does not consider the actual return
  type.
