Summary: This adds a new summary flag NotEligibleToImport that subsumes several existing flags (NoRename, HasInlineAsmMaybeReferencingInternal and IsNotViableToInline). It also subsumes the checking of references on the summary that was being done during the thin link by eligibleForImport() for each candidate. It is much more efficient to do that checking once during the per-module summary build and record it in the summary.
