[PATCH v3 09/19] Add assembler_name to cgraph_function_version_info.

[Alfie Richards]

This adds the assembler_name member to cgraph_function_version_info
to store the base assembler name for the function to be mangled. This is
used in later patches for refactoring FMV mangling.

gcc/ChangeLog:

        * cgraph.cc (cgraph_node::insert_new_function_version): Record
        assembler_name.
        * cgraph.h (struct cgraph_function_version_info): Add assembler_name.
