On Gen9+ there needs to be a header when sampling using SIMD4x2. The
header is set up by copying from the g0 register. Commit 07c571a39f
tried to fix this mov instruction to always use an exec size of 8
because previously it was incorrectly using 4. It did this by casting
the type of the destination register to vec8. This was done because
there is code in brw_set_dest to guess the exec size based on the
width of the dest register. However I misunderstood how this works
because it is actually only used when the width is less than 8. That
means the patch actually changed it to use the default exec size which
on SIMD16 would be 16 and the MOV would clobber over the first
register in the send message. This patch makes it additionally set the
default exec size to 8. This is similar to how the message is set up
in fs_generator::generate_tex.
I think this wasn't picked up by any Piglit tests because we don't
have any fragment shaders that hit this code path so nothing was using
SIMD16. However the patch caused failures in deqp tests.

The stage_abbrev and stage_name fields in backend_visitor provide what
we need without any additional effort. It also means we'll get the
right names for compute shaders, SIMD8 geometry shaders, and both kinds
of tessellation shaders.
This does unfortunately change the capitalization of the stage
abbreviation in the INTEL_DEBUG=optimizer output filenames. It doesn't
seem worth adding code to handle, though.

src1 would contain the predicate, which would get emitted as a register
source by an undiscerning srcId helper. Work around this in the same way

Original blorp writes only one buffer per shader invocation. Once
the launch mechanism is shared with glsl-based programs there will
be need for supporting multiple render targets.
Also drop the always constant color write disable settings.

Note that the magic number of one in gen7 logic is replaced by
BRW_SF_URB_ENTRY_READ_OFFSET ( == 1 also) for clarity.
On gen6 the change from zero to one (BRW_SF_URB_ENTRY_READ_OFFSET)
has no effect for native blorp as blorp doesn't use any
additional attributes. In fact, regular pipeline setup always
uses BRW_SF_URB_ENTRY_READ_OFFSET even when there are no additional
attributes. Hence the change makes the two (blorp and regular)
consistent.

The opt_sampler_eot optimisation of fs_visitor effectively assumes
that it is running on a fragment shader because it casts the program
key to a brw_wm_prog_key. However on Skylake fs_visitor can also be
used for vertex shaders. It looks like this usually works anyway
because the optimisation is skipped if key->nr_color_regions != 1.
However for a vertex shader the key is actually a brw_vs_prog_key so
the space for nr_color_regions is probably taken up by
key->base.program_string_id. This can end up making nr_color_regions
be 1 in which case the function will later assert when the last
instruction is not FS_OPCODE_FB_WRITE. This was making the DEQP test
suite assert. Presumably this only happens there because that compiles
a lot of shaders so it would end up with a high value for
program_string_id.

Previously binding an unitialized managed texture
was causing a crash, and a workaround was added to
prevent the crash.
This patch removes this workaround and instead set the initial
state of managed textures as dirty, so that when the texture is bound
for the first time, it is always initialized.

For D3DUSAGE_AUTOGENMIPMAP textures, applications can only
lock/copy from/get surface descriptor for/etc the first level.
Thus it makes sense to restrict the LOD to 0, and use only the first
level to generate the sublevels.
