Clang has a warning about overloading virtuals that triggers when a
derived class defines a virtual function that's an overload of
function in the base class. This kind of thing:
struct chart; // let's pretend this exists
struct Base
{
virtual void* get(char* e);
};
struct Derived: public Base {
virtual void* get(chart* e); // typo, we wanted to override the same function
};
The solution is to use
using Base::get;
to be explicit about the intention to reuse the base class virtual.
We hit this a lot with out glsl ir_hierarchical_visitor visitor
pattern, so let's adds some 'using' to calm down the compiler.

Here we use the NIR based builder to add everything to the resource
list execpt for SSO packed varyings. Since the details of those
varyings get lost during packing we leave the special handing to
the GLSL IR pass for now. In order to do this we add some bools
to the build resource list functions.
Using the NIR based resource list builder gets us a step closer to
using a native NIR based linker. It should also be faster than the
GLSL IR builder, one because the NIR optimisations should mean we
add less entries due to better optimisations, and two because nir
gives us better lists to work with and we don't need to walk the
entire IR to find the resources.

Currently the linker do all the work then check for the limits, which
means num_textures and num_images in shader_info may have to store more

To fix this, pull the check before we set the counts in shader_info.
Add necessary plumbing to make sure we bail once those errors are

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.
