PIC is `PassInstrumentationCallbacks`

I'm not too familiar with under what conditions it doesn't exist, but it's
canonical to check across CodeGen.
The passes don't need to be registered to run. They get scheduled by
`addAsmPrinterBegin` (and friends) inside of the `CodeGenPassBuilder`
implementation.
Registering them here just gives them names one can use for things like
`-start-before` or `-stop-after`.
