Summary: The NotEligibleToImport flag on the GlobalValueSummary was set if it isn't legal to import (e.g. because it references unpromotable locals) and when it can't be inlined (in which case importing is pointless). I split out the inlinable piece into a separate flag on the FunctionSummary (doesn't make sense for aliases or global variables), because in the future we may want to import for reasons other than inlining.
