To keep it completely customizable and without a separate pass instance, the third option is to have targets register their own name for the common AsmPrinterPass instance in a PB callback with `PIC->addClassToPassName(AsmPrinterPass::name(), "target-asm-printer")`
But we could go with the first option of predetermined target names to keep it simple.
