This patch updates the bitfields brw_context::wm.input_size_masks,
tracker::size_masks, and brw_wm_prog_key::proj_attrib_mask, all of
which are indexed by gl_frag_attrib, from 32-bit to 64-bit.
This paves the way for supporting geometry shaders, and for merging
the gl_frag_attrib and gl_vert_result enums. The combination of these
two will require at least 55 bits in the bitfields.

Untyped Atomic Operation messages are illegal for non-RAW formats. The
IVB hardware proceeds happily (after all, who cares what the format of the
surface is if you're doing untyped ops on it?), but later hardware
apparently doesn't. The simulator for gen7 does complain, though.

We're already walking the list, and we can easily know when something
has no reason to be in the list any longer, so take a brief extra step
to reduce our worst-case runtime (an oglconform test that emits the
maximum instructions in a fragment program). I don't actually know what
the worst-case runtime was, because it was too long and I got bored.

We were handling the the dependency workaround for the first written reg
of a send preceding the one we're fixing up, but didn't consider the other
regs. Thus if you had two sampler calls that got allocated to the same
set of regs, one might, rarely, ovewrite the other. This was occurring in
XBMC's GLSL shaders.

We were allowing a compressed instruction to write a register that
contained the last use of a uniform pull constant (either UBO load or push
constant spillover), so it would get half its values smashed.
Since we need to see the actual instruction to decide this, move the
pre-gen6 pixel_x/y logic here, which should improve the performance of
register allocation since virtual_grf_interferes() is called more than
once per instruction.

I don't see any reason for it -- it was introduced with the DRI2
invalidate work by krh in 2010 with no explanation. I suspect it was
something about wanting the same drm_intel_bo struct underneath multiple
openings of the BO within one process, but that's covered by libdrm at
this point. As far as the struct region goes, it is not threadsafe, so
multiple contexts sharing a region could have mixed up the map_count and
assertion failed or worse.

Again, eliminating a global variable in favor of a per-query object

Personally, I find this clearer: there's just the query object's BO,

If we haven't allocated a BO yet, we need to do that. Or, if there
isn't enough room to write another pair of values, we need to gather up
the existing results and start a new one. This is simple enough.
However, the old code was awkwardly split into two blocks, with a
write_depth_count() placed in the middle. The new depth count isn't
relevant to gathering the old BO's data, so that can go after the
reallocation is done. With the two blocks adjacent, we can merge them.

Since we already have an index in the brw_query_object, there's no need
to also keep a global variable that shadows it.
Plus, if we ever add support for more types of queries that still need
the per-batch before/after treatment we do for occlusion queries, we
won't be able to use a single global variable. In contrast, per-query
object variables will work fine.

This code was really difficult to follow, for a number of reasons:
- Queries were handled in four different ways (TIMESTAMP writes a single
value, TIME_ELAPSED writes a single pair of values, occlusion queries
write pairs of values for the start and end of each batch, and other
queries are done entirely in software. It turns out that there are
very good reasons each query is handled the way it is, but
insufficient comments explaining the rationale.
- It wasn't immediately obvious which functions were driver hooks
and which were helper functions. For example, brw_query_begin() is
a driver hook that implements glBeginQuery() for all query types, but
the similarly named brw_emit_query_begin() is a helper function that's
only relevant for occlusion queries.
Extra explanatory comments should save me and others from constantly
having to ask how this code works and why various query types are
handled differently.

For timestamp queries, we just write a single value to a BO. The

On Gen6, lower this to `ld` with lod=0 and an extra sample_index
parameter.
On Gen7, use `ld2dms`. We don't support CMS yet for multisample
textures, so we just hardcode MCS=0. This is ignored for IMS and UMS
surfaces.
Note: If we do end up emitting specialized shaders based on the MSAA
layout, we can emit a slightly shorter message here in the UMS case.
Note: According to the PRM, `ld2dms` takes one more parameter, lod.
However, it's always zero, and including it would make the message too
long for SIMD16, so we just omit it.

Gen7 has an erratum affecting the ld_mcs message, making it unsafe to
use when the surface doesn't have an associated MCS.
From the Ivy Bridge PRM, Vol4 Part1 p77 ("MCS Enable"):
"If this field is disabled and the sampling engine <ld_mcs>
message is issued on this surface, the MCS surface may be
accessed. Software must ensure that the surface is defined
to avoid GTT errors."
To allow the shader to treat all surfaces uniformly, force UMS if the
surface is to be used as a multisample texture, even if CMS would have
been possible.
