nir: Record info->fs.pixel_center_integer in lower_system_values

radeonsi uses a system value for gl_FragCoord rather than an input var.
These get translated into load_frag_coord NIR intrinsics, which lose the
pixel_center_integer and origin_upper_left decorations.  To cope with
this, Tim added a shader_info field for pixel_center_integer, and made
glsl_to_nir set it accordingly.

prog_to_nir also needs to handle these fragcoord conventions.  Instead
of duplicating the logic to set the info field, just move it to
nir_lower_system_values so it'll happen regardless of who makes the NIR.

(For what it's worth, we don't need an info flag for origin_upper_left,
because radeonsi lowers origin conventions in nir_lower_wpos_ytransform
before nir_lower_system_values destroys the variable and qualifiers.)

program: Extend prog_to_nir handle system values.

Some drivers, such as radeonsi, use a system value for gl_FragCoord
rather than an input variable.  In this case, our Mesa IR will have
a PROGRAM_SYSTEM_VALUE register, which we need to translate.

This makes prog_to_nir work for Gallium drivers which expose the
PIPE_CAP_TGSI_FS_POSITION_IS_SYSVAL capability bit.

program: Use u_bit_scan64 in prog_to_nir.

st/nir: Make new helpers for constructing built-in NIR shaders.

The state tracker generates several built-in shaders in order to
perform scissored clears, upload/download PBOs, and so on.  These
are currently constructed using TGSI, using ureg and u_simple_shader.

I want to have NIR versions of these shaders, for my Gallium driver
that has a NIR backend but no TGSI support.  To that end, we'll want
a few helpers to help construct simple shaders.

This patch adds two new helpers:

- st_nir_finish_builtin_shader() takes a manually constructed NIR
  shader, applies lowering passes (like st_link_nir would do for GLSL),
  and constructs the pipe_shader_state.

- st_nir_make_passthrough_shader() makes a simple passthrough shader,
  which copies inputs to outputs.  This is similar to u_simple_shaders.

nir: Move V3D's "the shader was TGSI, ignore FS output types" flag to NIR.

Ken's rework of mesa/st builtins to NIR means that we'll have more NIR
shaders with color output types that are mismatched with the render target
types.  Since this is behavior that GLSL doesn't require, add it as a
shader_info option so the driver can know that it needs to ignore the FS
output's base type in favor of the actual render target's.  This prevents
needing additional variants in several mesa/st paths (clear, pbo upload,

for any TGSI being passed to it (from u_blitter, for example).

Previously, we only applied the fix to shaders with a dispatch mode of
SIMD8 but the code it relies on for SIMD16 mode only applies to SIMD16
instructions.  If you have a SIMD8 instruction in a SIMD16 shader,
neither would trigger and the restriction could still be hit.

intel/fs: Properly handle 64-bit types in LOAD_PAYLOAD

By just assigning dst.type to src[i].type, we ensure that the offset at
the end of the loop actually offsets it by the right number of
registers.  Otherwise, we'll get into a case where we copy with a Q type
and then offset with a D type and things get out of sync.

intel/fs/cse: Split create_copy_instr into three cases

Previously, we tried to combine all cases where the instruction being

a bit of special casing for LOAD_PAYLOAD.  This commit splits things so
that LOAD_PAYLOAD is entirely it's own case.  This makes tweaking the
LOAD_PAYLOAD case simpler in the next commit.

We already defer handling the actual execution modes until after we've

spirv: Rework handling of spec constant workgroup size built-ins

Instead of handling it as part of the handling of constant instructions,
just stash the vtn_value when we see the decoration and handle it
explicitly later.  This will let us re-order handling of constant
instructions without breaking the Vulkan SPIR-V requirement that
decorating a specialization constant as the WorkgroupSize built-in
overrides the workgroup size set as an execution mode.

spirv: Replace vtn_constant_value with vtn_constant_uint

The uint version is less typing, supports different bit sizes, and is

st/glsl_to_nir: remove dead local variables

Without this we do not end up with a deterministic NIR because
temporary register variables are added in random order. NIR must
be deterministic because we use it to produce a sha for the
radeonsi backends disk cache.

This fixes the shader cache for a bunch of shaders.

Another positive is that this results in a large reduction in the
size of the NIR that the state tracker stores to the disk cache.

meson: remove -std=c++11 from intel/tools

for meson all C++ code is already compiled as C++11, so it's
unnecessary. It's also the wrong way to do this, if we really needed
this the correct way is to set:

```meson
executable(

Which ensures not only that the correct syntax for the current
