i965/fs: Reduce the response length of sampler messages on Skylake.

Often, we don't need a full 4 channels worth of data from the sampler.
For example, depth comparisons and red textures only return one value.
To handle this, the sampler message header contains a mask which can
be used to disable channels, and reduce the message length (in SIMD16
mode on all hardware, and SIMD8 mode on Broadwell and later).

We've never used it before, since it required setting up a message
header.  This meant trading a smaller response length for a larger
message length and additional MOVs to set it up.

However, Skylake introduces a terrific new feature: for headerless
messages, you can simply reduce the response length, and it makes
the implicit header contain an appropriate mask.  So to read only
RG, you would simply set the message length to 2 or 4 (SIMD8/16).

This means we can finally take advantage of this at no cost.

i965: Don't force a header for texture offsets of 0.

Calling textureOffset() with an offset of <0, 0, 0> is equivalent to
calliing texture().  We don't actually need to set up an offset,
which causes a message header to be created.

A fairly common pattern is to sample at a point with a bunch of
offsets, and average them.  It's natural to write all the lookups
as textureOffset, but use <0, 0> for the center sample.

i965/blorp: Refactor to get rid of the get_wm_prog virtual function

Instead of having a virtual member function for getting the WM/PS kernel,
we simply add fields for prog_data and the kernel to brw_blorp_parms and
always make sure those get set as part of the different constructors.

v2: Use use prog_data != NULL to check for a valid program instead of a
    magic kernel offset value
