For dvec3 and dvec4 types, a single GRF do not have enough space to
allocate two inputs from two different vertices (SIMD4x2).
So the GRF only contains first two components for the two vertices, and
the next GRF has the remaining components.
We want to put all the components for the same vertex in the same
register. Thus, we do a shuffle to reorder the data.

As part of the payload setup, setup_attributes is called with the first
GRF that can be used for the attributes (first ones are used for
uniforms for example) and returns the first GRF that is not part of the
payload. Before this patch, it adds directly the number of attributes.
But as with 64-bit attributes can consume more than one slot, that is
not valid anymore. This patch change the addition to use the number of
slots consumed.
gen >= 8 would not be affected, as they use the scalar mode. For that
case, the vs configuration is done at fs_visitor::assign_vs_urb_setup.

Annoyingly, SPIR-V lets you specify all of these fields in either the
TCS or TES, which means that we need to be able to store all of them
for either shader stage. Putting them in a union won't work.
Combining both is an easy solution, and given that the TCS struct only
had a single field, it's pretty inexpensive.
This patch renames the combined struct to "tess" to indicate that it's
for tessellation in general, not one of the two stages.

We want vue_map->num_slots to be one more than the final slot.
When assigning fixed slots, built-in slots, and non-SSO user varyings,
we do slot++. This leaves "slot" as one past the most recently assigned
slot. But for SSO user varyings, we computed slot based on the varying
location value...and left it at that slot value.
To work around this inconsistency, I made num_slots be "slot + 1" if
separate and "slot" otherwise. The problem is...if there are no user
varyings in SSO mode...then we would have done slot++ when assigning
built-ins, so it would be off by one. This resulted in loops from 0
to vue_map->num_slots hitting a bonus BRW_VARYING_SLOT_PAD at the end.
This used to break the SIMD8 VS/TES backends, but I fixed that in
commit 480d6c1653713dcae617ac523b2ca5deee01c845. It's probably safe
at this point, but we should fix it anyway.
To fix this, do slot++ in all cases. For SSO mode, we overwrite slot
for every varying, so this increment only matters on the last varying.
Because we process varyings in order, this will set slot to 1 more
than the highest assigned slot.

So far, input_reads was a bitmap tracking which vertex input locations
were being used.
In OpenGL, an attribute bigger than a vec4 (like a dvec3 or dvec4)
consumes just one location, any other small attribute. So we mark the
proper bit in inputs_read, and also the same bit in double_inputs_read
if the attribute is a dvec3/dvec4.
But in Vulkan, this is slightly different: a dvec3/dvec4 attribute
consumes two locations, not just one. And hence two bits would be marked
in inputs_read for the same vertex input attribute.
To avoid handling two different situations in NIR, we just choose the
latest one: in OpenGL, when creating NIR from GLSL/IR, any dvec3/dvec4
vertex input attribute is marked with two bits in the inputs_read bitmap
(and also in the double_inputs_read), and following attributes are
adjusted accordingly.
As example, if in our GLSL/IR shader we have three attributes:
layout(location = 0) vec3 attr0;
layout(location = 1) dvec4 attr1;
layout(location = 2) dvec3 attr2;
then in our NIR shader we put attr0 in location 0, attr1 in locations 1
and 2, and attr2 in location 3 and 4.
Checking carefully, basically we are using slots rather than locations
in NIR.
When emitting the vertices, we do a inverse map to know the
corresponding location for each slot.
v2 (Jason):
- use two slots from inputs_read for dvec3/dvec4 NIR from GLSL/IR.
v3 (Jason):
- Fix commit log error.
- Use ladder ifs and fix braces.
- elements_double is divisible by 2, don't need DIV_ROUND_UP().
- Use if ladder instead of a switch.
- Add comment about hardware restriction in 64bit vertex attributes.

We run this after nir_lower_vars_to_ssa so that as many load/store_var

Broadwell had similar results. On older hardware, the impact isn't as
large because they don't advertise GL 4.5. Of the hurt programs, all but
one are hurt by a single instruction and the one is hurt by 3 instructions.
All of the helped programs, on the other hand, are helped by at least 3
instructions and one kerbal space program shader is helped by 44.59%.
The real star of the show, however, is the Gl43CSDof synmark2 benchmark
which has two shaders which are cut by 28% and 40% and the over-all runtime
performance of the benchmark on my Sky Lake laptop is improved by around
25-30% (it's a bit hard to be exact due to thermal throttling).

Treating everything as scalar arrays allows us to drop a bunch of
special case input/output munging all throughout the backend.
Instead, we just need to remap the TessLevel components to the
appropriate patch URB header locations in remap_patch_urb_offsets().
We also switch to treating the TES input versions of these as ordinary
shader inputs rather than system values, as remap_patch_urb_offsets()
just makes everything work out without special handling.
This regresses one Piglit test:
arb_tessellation_shader-large-uniforms/GL_TESS_CONTROL_SHADER-array-at-limit
The compiler starts promoting the constant arrays assigned to gl_TessLevel*
to uniform arrays. Since the shader also has a uniform array that uses
the maximum number of uniform components, this puts it over the uniform
component limit enforced by the linker. This is arguably a bug in the
constant array promotion code (it should avoid pushing us over limits),
but is unlikely to penalize any real application.

This is harmless today because gl_TessLevelInner/Outer in the TES is
currently treated as system values. However, when we move to treating
them as inputs, this would cause a bug: with no TCS present, it would
propagate TES reads of VARYING_SLOT_TESS_LEVEL into the VS output VUE
map slots. This is totally bogus - those don't even exist in the VS.

This will help allow us to store pointers to gl_program structs in the
CurrentProgram array resulting in a bunch of code simplifications.

This also removes the duplicate field in gl_linked_shader, and
gets num_ubos from shader_info instead.

Having it here rather than in gl_linked_shader allows us to simplify
the code.
Also it is error prone to depend on the gl_linked_shader for programs
in current use because a failed linking attempt will free infomation
about the current program. In i965 we could be trying to recompile
a shader variant but may have lost some required fields.
We drop the memset on ImageUnits because gl_program is already
created using rzalloc().
