    rs6000: Fix rs6000_atomic_assign_expand_fenv [PR94826]

    This is the rs6000 version of the earlier committed x86, aarch64 and arm
    fixes, as create_tmp_var_raw is used because the C FE can call this outside
    of function context, we need to make sure the first references to those
    VAR_DECLs are through a TARGET_EXPR, so that it gets gimple_add_tmp_var
    marked in whatever function it gets expanded in.  Without that DECL_CONTEXT
    is NULL and the vars aren't added as local decls of the containing
function.

            * config/rs6000/rs6000.c (rs6000_atomic_assign_expand_fenv): Use
            TARGET_EXPR instead of MODIFY_EXPR for first assignment to
            fenv_var, fenv_clear and old_fenv variables.  For fenv_addr
            take address of TARGET_EXPR of fenv_var with void_node initializer.
