i965/skl: In opt_sampler_eot always set destination register to null

opt_sampler_eot enables a direct write to framebuffer from a sample.
In order to do this the sample message needs to have a message header
so if there wasn't one already then the function adds one. In addition
the function sets the destination register to null because it's no

The effective_width field was an ill-concieved hack to get around issues in

i965/fs: Rework the fs_visitor LOAD_PAYLOAD instruction

The newly reworked instruction is far more straightforward than the
original.  Before, the LOAD_PAYLOAD instruction was lowered by a the
complicated and broken-by-design pile of heuristics to try and guess
force_writemask_all, exec_size, and a number of other factors on the
sources.

Instead, we use the header_size on the instruction to denote which sources
are "header sources".  Header sources are required to be a single physical
hardware register that is copied verbatim.  The registers that follow are
considered the actual payload registers and have a width that correspond's
to the LOAD_PAYLOAD's exec_size and are treated as being per-channel.  This
gives us a fairly straightforward lowering:

 1) All header sources are copied directly using force_writemask_all and,
    since they are guaranteed to be a single register, there are no
    force_sechalf issues.

 2) All non-header sources are copied using the exact same force_sechalf
    and force_writemask_all modifiers as the LOAD_PAYLOAD operation itself.

 3) In order to accommodate older gens that need interleaved colors,
    lower_load_payload detects when the destination is a COMPR4 register
    and automatically interleaves the non-header sources.  The
    lower_load_payload pass does the right thing here regardless of whether
    or not the hardware actually supports COMPR4.

This patch commit itself is made up of a bunch of smaller changes squashed
together.  Individual change descriptions follow:

i965/fs: Rework fs_visitor::LOAD_PAYLOAD

   We rework LOAD_PAYLOAD to verify that all of the sources that count as
   headers are, indeed, exactly one register and that all of the non-header
   sources match the destination width.  We then take the exec_size for
   LOAD_PAYLOAD directly from the destination width.

i965/fs: Make destinations of load_payload have the appropreate width

i965/fs: Rework fs_visitor::lower_load_payload

   v2: Don't allow the saturate flag on LOAD_PAYLOAD instructions

i965/fs_cse: Support the new-style LOAD_PAYLOAD

i965/fs_inst::is_copy_payload: Support the new-style LOAD_PAYLOAD

i965/fs: Simplify setup_color_payload

   Previously, setup_color_payload was a a big helper function that did a
   lot of gen-specific special casing for setting up the color sources of
   the LOAD_PAYLOAD instruction.  Now that lower_load_payload is much more
   sane, most of that complexity isn't needed anymore.  Instead, we can do
   a simple fixup pass for color clamps and then just stash sources
   directly in the LOAD_PAYLOAD.  We can trust lower_load_payload to do the
   right thing with respect to COMPR4.

i965/fs_inst: Add an is_copy_payload helper

This commit adds a new is_copy_payload helper to fs_inst that takes the
place of the similarly named functions in cse and register coalesce.  The
two is_copy_payload functions in CSE and register coalesce were subtly
different and potentially subtly broken.  The new version unifies the two
and should be more correct.

i965/fs: Make half(fs_reg, unsigned) handle register files more explicitly

Previously, we had a special case for uniforms and immediates and then a
bunch of asserts for various other pessimal things.  This commit changes it
so that it explicitly does something on each register file.  Some of them
are disallowed and others are treated properly.
