ICEs in convert_move on x86_64.  Works with 4.3 or 4.5.

Trunk has

          if (COMPLEX_MODE_P (TYPE_MODE (TREE_TYPE (from))))

instead of the 4.4

          if (TREE_CODE (TREE_TYPE (from)) == COMPLEX_TYPE)


Fixed by

2009-06-17  Steve Ellcey  <sje@cup.hp.com>

        * expr.c (expand_assignment): Change complex type check.

Indeed, that fixes it.  Going to bootstrap/regtest it now on several arches,
then commit before rolling 4.4.3-rc1.
