[AsmPrinter] Make OpAsmPrinter::printFunctionalType be resilient to null values.

Authored by lattner on Dec 29 2020, 11:05 AM.



A previous patch made Value::getType() be resilient to null values which was
considered to be too sweeping. This is a more targeted change which requires
deabstracting some templates.

A middle ground would be to make ValueTypeIterator be tolerant to null values.

Should this use a different variable name for the "Value op" argument to the lambda since there exists "Operation *op" as well? I was initially confused due to the name reuse here.

nit: Spell out auto here or just inline the op->getNumResults() into the check below.
