i965/vec4: Use the sampler for pull constant loads on Broadwell.

We've used the LD sampler message for pull constant loads on earlier
hardware for some time, and also were already using it for the FS on
Broadwell.  This patch makes us use it for Broadwell VS/GS as well.

I believe that when I wrote this code in 2012, we still used the data
port in some cases, and I somehow neglected to convert it while
rebasing.

Improves performance in GLBenchmark 2.7 Egypt by 416.978% +/- 2.25821%
(n = 17).  Many other applications should benefit similarly: this speeds
up uniform array access in the VS, which is commonly used for skinning
shaders, among other things.

i965/vec4: Fix dead code elimination for VGRFs of size > 1.

When faced with code such as:

    mov vgrf31.0:UD, 960D
    mov vgrf31.1:UD, vgrf30.xxxx:UD

The dead code eliminator didn't consider reg_offsets, so it decided that
the second instruction was writing was writing to the same register as
the first one, and eliminated the first one.  But they're actually
different registers.

This fixes INTEL_DEBUG=shader_time for vertex shaders.  In the above
code, vgrf31.0 represents the offset into the shader_time buffer where
the data should be written, and vgrf31.1 represents the actual time
data.  With a completely undefined offset, results were...unexpected.

I think this is probably one of the few cases (maybe only case) where we
generate multiple MOVs to a large VGRF.  Normally, we just use them as
texturing results; the other SEND-from-GRF uses a size 1 VGRF.
