[PATCH] Linearize initializer

[PATCH] Linearize initializer

Here is a tentative patch to do initializer linearizations properly.

While I am learning the new initializer tree.  I think the current way
of initializing does not handle the bit field member correctly.  I can't
tell from the initializer tree that a member is a bit field.  Do I miss
some thing?

[ Linus' note: "expr->ctype" should have the type of the individual assignment (and
  thus the bitfield), but maybe I'm wrong.

  So check that first, but if I'm full of sh*t, we probably need to make
  the offset be a bit-offset in the EXPR_POS thing, and add a size field
  too.  ]

Anyway, here is the patch works for non bit field.
