...;> already been loaded in the main module. The essential things I want to accomplish with this part: - Make `type:` operands less special: instead of referencing types indirectly through MDString, point directly at the type node. - Stop using `retainedTypes:` by default (only for -gfull, etc.). - Avoid blowing up memory in -flto=full (which converting MDString references back to pointers would do naively, through re-introducing cycles). Note that this needs to be handled somehow at BitcodeReader time. After chatting with Eric, I don't think this conflicts at a...
