There were a number of bugs related to the pairing of vector and scalar
operations where swizzles ended up using the wrong source register,
or an instruction was moved forward and ended up overwriting an aliased
register.

The new algorithm for register allocation is quite conservative and may
run out of registers before necessary. On the plus side, It Just Works.

Pairing is done whenever possible, and in more cases than before, so
in practice this change should be a net win.

i915tex: Fix triple buffering after recent Mesa core changes.

Remove superfluous _mesa_resize_framebuffer call which is now harmful because
it causes the third renderbuffer to have width/height 0, so Mesa refuses to
render to it.

In the long term, it would be nice to remove the hack in
intel_alloc_window_storage in favour of a proper Mesa interface for flipping
between more than two colour buffers.
