[Bug tree-optimization/15731] [3.5 Regression] Invalid operand to binary operator ICE when __builtin_va_arg is used

[pinskia at gcc dot gnu dot org]

Confirmed, I will note this was broken by:
2004-05-21  Richard Henderson  <rth@redhat.com>
        
        * gimplify.c (mostly_copy_tree_r): Don't attempt to copy decls.
        (copy_if_shared_r): Don't copy decls, types, constants, BINDs.
        Don't mark VA_ARG_EXPRs volatile here.
        (gimplify_modify_expr): Unshare TYPE_SIZE_UNIT.

I will also note it was fixed at one point, see PR 14498.
