At this point we have a
CrateInfofor the target which contains the name of the crate, regardless whether it's been derived from thectx.attr.crate_nameor explicitly assigned. The code without this PR works well for therules_rust, because theCrateInfo.crate_nameis obtained by calling theget_crate_name_from_attrfunction. However, this is not sufficient for aspects, as they may be attached to a target that doesn't specify crate name, or one may want to assign a modified name to crates created by aspects.
