    arm: Handle fixed PIC register in require_pic_register (PR target/115485)

    Commit r9-4307-g89d7557202d25a forgot to accept a fixed PIC register
    when extending the assert in require_pic_register.

    arm_pic_register can be set explicitly by the user
    (e.g. -mpic-register=r9) or implicitly as the default value with
    -fpic/-fPIC/-fPIE and -mno-pic-data-is-text-relative -mlong-calls, and
    we want to use/accept it when recording cfun->machine->pic_reg as used
    to be the case.

            PR target/115485
            gcc/
            * config/arm/arm.cc (require_pic_register): Fix typos in
            comment. Handle fixed arm_pic_register.
