commit 93a83a8e51a92699948ba322c22d071e89d0eedf
Author: Alfie Richards <alfie.richa...@arm.com>
Date:   Fri Jan 31 11:47:57 2025 +0000

    Add clone_identifier function.
    
    This is similar to clone_function_name and its siblings but takes an
    identifier tree node rather than a function declaration.
    
    This is to be used in conjunction with the identifier node stored in
    cgraph_function_version_info::assembler_name to mangle FMV functions in
    later patches.
    
    gcc/ChangeLog:
    
            * cgraph.h (clone_identifier): New function.
            * cgraphclones.cc (clone_identifier): New function.
            clone_function_name: Refactored to use clone_identifier.
