to cross the separate compilation boundary.
-So a IfaceLetBndr keeps a trimmed-down list of IfaceIdInfo stuff.
-Currently we only actually retain InlinePragInfo, but in principle we could
-add strictness etc.

+In general we retain all info that is left by CoreTidy.tidyLetBndr, since
+that is what is seen by importing module with --make
