* gimplify.c (gimplify_one_sizepos): For is_gimple_constant (expr)
return early, inline manually is_gimple_sizepos. Make sure if we
call gimplify_expr we don't end up with a gimple constant.
* tree.c (variably_modified_type_p): Don't return true for
is_gimple_constant (_t). Inline manually is_gimple_sizepos.
* gimplify.h (is_gimple_sizepos): Remove.
