i965: Reduce passing 2x32b of reloc_domains to 2 bits

The kernel only cares about whether the object is to be written to or
not, only reduces (reloc.read_domains, reloc.write_domain) down to just
!!reloc.write_domain. When we use NO_RELOC, the kernel doesn't even read
those relocs and instead userspace has to pass that information in the
execobject.flags. We can simplify our reloc api by also removing the
unused read/write domains and only pass the resultant flags.

The caveat to the above are when we need to make the kernel aware that
certain objects need to take into account different work arounds.
Previously, this was done using the magic (INSTRUCTION, INSTRUCTION)
reloc domains. NO_RELOC requires this to be passed in the execobject
flags as well, and now we push that up the callstack.

The API is more compact, more expressive of what happens underneath, but
unfortunately requires more knowledge of the system at the point of use.
Conversely it also means that knowledge is specific and not generally
applied and so not overused.

i965: Convert reloc.target_handle into an index for I915_EXEC_HANDLE_LUT

Based on a patch by Chris Wilson (who also wrote this commit message).

Passing the index of the target buffer via the reloc.target_handle is
marginally more efficient for the kernel (it can avoid some allocations,
and can use a direct lookup rather than a hash or search). It is also
useful for ourselves as we can use the index into our exec_bos for other
tasks.

i965: Ignore reloc read/write domains

Since before the kernel supported I915_EXEC_NO_RELOC, long before our
minimum kernel requirement, the kernel unconditionally invalidated all
GPU TLBs before a batch and flushed all GPU caches after a batch. At
that moment, the only use for read/write domain was for activity
tracking, ensuring that future reads waited for the last writer and
future writes waited for all reads. This only requires a single bit in
the execbuf interface which can be supplied via the NO_RELOC interface,
making the use of relocation domains entirely redundant.

Trimming the excess writes into the array allows the compiler to be much
more frugal:

st/mesa: fix handling of NumSamples=1 (v2)

In Mesa we use the convention that if gl_renderbuffer::NumSamples
or gl_texture_image::NumSamples is zero, it's a non-MSAA surface.
Otherwise, it's an MSAA surface.  But in gallium nr_samples=1 is a
non-MSAA surface.

Before, if the user called glRenderbufferStorageMultisample() or
glTexImage2DMultisample() with samples=1 we skipped the search for the
next higher number of supported samples and asked the gallium driver to
create a surface with nr_samples=1.  So we got a non-MSAA surface.
This failed to meet the expection of the user making those calls.

This patch changes the sample count checks in st_AllocTextureStorage()
and st_renderbuffer_alloc_storage() to test for samples > 0 instead of > 1.
And we now start querying for MSAA support at samples=2 since gallium has
no concept of a 1x MSAA surface.

A specific example of this problem is the Piglit arb_framebuffer_srgb-blit
test.  It calls glRenderbufferStorageMultisample() with samples=1 to
request an MSAA renderbuffer with the minimum supported number of MSAA
samples.  Instead of creating a 4x or 8x, etc. MSAA surface, we wound up
creating a non-MSAA surface.

Finally, add a comment on the gl_renderbuffer::NumSamples field.

There is one piglit regression with the VMware driver:
ext_framebuffer_multisample-blit-mismatched-formats fails because
now we're actually creating 4x MSAA surfaces (the requested sample
count is 1) and we're hitting some sort of bug in the blitter code.  That
will have to be fixed separately.  Other drivers may find regressions
too now that MSAA surfaces are really being created.

v2: start quering for MSAA support with samples=2 instead of 1.

i965: Set "Subslice Hashing Mode" to 16x16 on Apollolake.

As of 4.11, the kernel isn't bothering to set the subslice hashing mode
on Apollolake, leaving it at the default of 8x8.  (It initializes it to
16x4 on most platforms.)

Performance data for GPUTest Triangle on Apollolake at 1024x640:

   X-tiled RT:
   -----------
   8x8 -> 16x4:   2.4325%  +/- 0.383683% (n=107)
   8x8 -> 8x4:   -3.75105% +/- 0.592491% (n=40)
   8x8 -> 16x16:  6.17238% +/- 0.67157%  (n=30)

   Y-tiled RT:
   -----------
   8x8 -> 16x4:   1.30307%  +/- 0.297292% (n=205)
   8x8 -> 8x4:   -0.769282% +/- 0.729557% (n=35)
   8x8 -> 16x16:  3.00254%  +/- 0.715503% (n=40)

   8x MSAA RT (INTEL_FORCE_MSAA=8):
   --------------------------------
   8x8 -> 16x4:   1.38889% +/- 0.93729%  (n=7)
   8x8 -> 8x4:   -2.10643% +/- 1.15153%  (n=3)
   8x8 -> 16x16:  3.87183% +/- 1.08851%  (n=5)

Based on this, we choose 16x16 for Apollolake.

Skylake GT2 with X-tiled buffers appears to be a toss-up between 16x4
and 16x16, and with Y-tiled buffers it doesn't seem to really matter.
So we'll leave Skylake alone for now.

The hashing mode doesn't seem to make a measurable impact on more
complex benchmarks.
