[Bug c/17957] [4.0 regression] vector type node used after garbage-collected

An easy fix is for build_word_mode_vector_type to not try to reuse types.
The change to the garbage collector merely exposed a latent bug.

It works for me if build_word_mode_vector_type is cut down to this, although
there's probably a cleaner place to fix it:

static tree
build_word_mode_vector_type (int nunits)
{
  static tree innertype;
                                                                                
  if (!innertype)
    innertype = lang_hooks.types.type_for_mode (word_mode, 1);
  return build_vector_type (innertype, nunits);
}
