    pretty_printer: unbreak build on aarch64 [PR115465]
    
    I missed this target-specific usage of pretty_printer::buffer when
    making the fields private in r15-1209-gc5e3be456888aa; sorry.

            PR bootstrap/115465
            * config/aarch64/aarch64-early-ra.cc (early_ra::process_block):
            Update for fields of pretty_printer becoming private in
            r15-1209-gc5e3be456888aa.
