It's intel-specific, used to get at MSAA compression information.

This cleans up a bunch of gross sprintfs and keeps the caller from needing
to remember to ralloc_strdup. I added a couple of '"%s", name ? name :
""' to radv where I didn't fully trace through whether a non-null name was
being passed in.
I also took the liberty of adding a basic name to a few shaders (pan_blit,
unit tests)

These two consumers were the only ones out of the ~65 calls to
init_simple_shader, so there's a pretty clear consensus on how to allocate
simple shaders. I suspect that actually these would be just fine with
b.shader being the mem_ctx, but that would take a bit more rework.

It's kind-of an anomaly that the Intel drivers are still treating
gl_FragCoord as an input. It also makes zero sense because we have to
special-case it in the back-end.
Because ANV is the only user of nir_lower_wpos_center, we go ahead and
just update it to look for nir_intrinsic_load_frag_coord as part of this
patch.

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
modes")
v2: (Jason)
* glsl_to_nir: get the info before glsl_to_nir, while all the rest
of the info gathering is happening
* prog_to_nir: gather the info on a general info-gathering pass,
not on variable setup.
v3: (Jason)
* Squash with the patch that removes that info from ir variable
* anv: assert that OriginUpperLeft is true. It should be already
set by spirv_to_nir.
* blorp: set origin_upper_left on its core "compile fragment
shader", not just on some specific places (for this we added an
helper on a previous patch).
* 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.
v4: (reported by failing gitlab pipeline #18750)
* state_tracker: update too due changes on ir.h/gl_program
v5:
* blorp: minor change after change on previous patch
* radeonsi: update due this change.
v6: (Timothy Arceri)
* prog_to_nir: remove extra whitespace
* shader_info: don't use :1 on origin_upper_left
* glsl: program.fs.origin_upper_left/pixel_center_integer can be
move out of the shader list loop
This initializes the nir shader that will be used by blorp. Right now
it doesn't do too much beyond calling nir_builder_init_simple_shader,
and setting a name. More stuff will be added on following patches.
v2: there is a case were it is used a VERTEX_SHADER (Alejandro)
