IRGen: Nuke isSILOnly usage

It queried for [transparent] [serialized] definitions and only had an effect
when the module was compiled with -Onone because we remove [serialized]
as part of the optimizer pipeline.

It was causing bad effects when the module we imported from was compiled
with -Onone:

 The definition would be marked internal in said module.

and the importing module is compile with -O:

 The definition would be marked as available_externally.

because neither would guaranteed the presence of a definition of the
imported symbol available to the importer.
