For OpenCL we never want to strip the info from the types, and it makes
type comparisons easier in later stages. We might later need a nir pass to
strip this for GLSL, but so far the only regression is the assert and Jason
said removing that is fine.

This reverts commit db57db5317. When
building IR, nothing is really immutable and, since C has no concept of
constness propagating beyond the first pointer, we have to be vary
careful with how we use it. To just throw const into a function like
this is a lie.
Instead, we should just drop the unneeded const in spirv_to_nir which
this commit does along with the revert.
the idea here is to generate an entry point stub function wrapping around the
actual kernel function and turn all parameters into shader inputs with byte
addressing instead of vec4.
This gives us several advantages:
1. calling kernel functions doesn't differ from calling any other function
2. CL inputs match uniforms in most ways and we can just take advantage of most
of nir_lower_io
v2: move code into a seperate function

When emitting a branch in a block, it does not make sense to continue
processing further instructions, as they will not be reachable.
This fixes a nasty case with a loop with a branch that both then-part
and else-part exits the loop:
%1 = OpLabel
OpLoopMerge %2 %3 None
OpBranchConditional %false %2 %2
%3 = OpLabel
OpBranch %1
%2 = OpLabel
[...]
We know that block %1 will branch always to block %2, which is the merge
block for the loop. And thus a break is emitted. If we keep continuing
processing further instructions, we will be processing the branch
conditional and thus emitting the proper NIR conditional, which leads to
instructions after the break.
This fixes dEQP-VK.graphicsfuzz.continue-and-merge.

On GLSL that info is set as a layout qualifier when redeclaring
gl_FragCoord, so somehow tied to a specific variable. But in practice,
they behave as a global of the shader. On ARB programs they are set
using a global OPTION (defined at ARB_fragment_coord_conventions), and
on SPIR-V using ExecutionModes, that are also not tied specifically to
the builtin.
This patch moves that info from nir variable and ir variable to nir
shader and gl_program shader_info respectively, so the map is more
similar to SPIR-V, and ARB programs, instead of more similar to GLSL.
FWIW, shader_info.fs already had pixel_center_integer, so this change
also removes some redundancy. Also, as struct gl_program also includes
a shader_info, we removed gl_program::OriginUpperLeft and
PixelCenterInteger, as it would be superfluous.
This change was needed because recently spirv_to_nir changed the order
in which execution modes and variables are handled, so the variables
didn't get the correct values. Now the info is set on the shader
itself, and we don't need to go back to the builtin variable to set
it.
Fixes: e68871f6a ("spirv: Handle constants and types before execution

* prog_to_nir: no need to gather specifically this fragcoord modes
as the full gl_program shader_info is copied.
* spirv_to_nir: assert that we are a fragment shader when handling
this execution modes.

Under Vulkan, the double vertex attributes take up the same size
regardless of whether they are vertex inputs or any other stage

Under OpenGL (ARB_gl_spirv), from GLSL 4.60 spec, section 4.3.9
Interface Blocks:
"It is a compile-time error to have an input block in a vertex
shader or an output block in a fragment shader. These uses are
reserved for future use."
So we also don't need to check if it is an vertex input or not, and
use false in any case.

Previously the code was taking any location decoration on the block
and using that to calculate the member locations for all of the
members. I think this was assuming that there would only be one
location decoration for the entire block. According to the Vulkan spec
it is possible to add location decorations to individual members:
“If the structure type is a Block but without a Location, then each
of its members must have a Location decoration. If it is a Block
with a Location decoration, then its members are assigned
consecutive locations in declaration order, starting from the
first member which is initially the Block. Any member with its own
Location decoration is assigned that location. Each remaining
member is assigned the location after the immediately preceding
member in declaration order.”
This patch makes it instead keep track of which members have been
assigned an explicit location. It also has a space to store the
location for the struct as a whole. Once all the decorations have been
processed it iterates over each member to fill in the missing
locations using the rules described above.
So, this commit is needed to get working a case like this, on both
Vulkan and OpenGL using SPIR-V (ARB_gl_spirv):
out block {
layout(location = 2) vec4 c;
layout(location = 3) vec4 d;
layout(location = 0) vec4 a;
layout(location = 1) vec4 b;
} name;
