    Do not use caller-saved registers for COMDAT functions

    A reference to a COMDAT function may be resolved to another definition
    outside the current translation unit, so it's not eligible for `-fipa-ra`.

    In `decl_binds_to_current_def_p()` there is already a check for weak
    symbols. This commit checks for COMDAT functions that are not implemented
    as weak symbols, for example, on *-*-mingw32.

    gcc/ChangeLog:

            PR rtl-optimization/115049
            * varasm.cc (decl_binds_to_current_def_p): Add a check for COMDAT
            declarations too, like weak ones.
