In #90037, ClangImporter is updated to fix the CodeGen target info when using directCC1 mode. This causes some regression on specific platforms for emitPCM actions. EmitPCM action in explicit module build only get a minimal set of the swift flags and on some platforms the minimal flags cannot generate clang driver arguments that can be accepted by ClangImporter. The fix is to not regenerating driver arguments for CodeGen target options when there are no CodeGen is in the RequestedAction. This also saves the unnecessary round trip into clang driver when CodeGenOption is not needed. rdar://181058499
