  [NFC][CodeGen] Create method to clear registers (#66958)

Place the architecuture-specific logic to clear registers in a single
place and call it via a TargetInstrInfo method.

This will allow one to add instructions to clear registers holding the
stack protector guard value before return, but do it in
non-architecture-specific code.
