[IR] AutoUpgrade ModuleFlagBehavior for PIC and PIE level
Summary: From r303590, ModuleFlagBehavior for PIC and PIE level is changed from Error to Max. This will cause bitcode compatibility issue when linking against a bitcode static archive built with old compiler. Add an auto-ugprade path to upgrade the the ModuleFlagBehavior in the old bitcode to match the new one so IRLinker can link them.
