First we move double_inputs_read into a vs struct in the union,
double_inputs_read is only used for vs inputs so this will
save space and also allows us to add a new double_inputs field.
We add the new field because c2acf97fcc9b changed the behaviour
of double_inputs_read, and while it's no longer used to track
actual reads in i965 we do still want to track this for gallium
drivers.

To avoid any vulkan driver to include the GL mtypes.h. Renamed as
eventually this could be used by drivers not using nir.
v2: remove compiler/spirv/spirv.h from mtypes (Alejandro)
v3: added the definition at compiler/shader_info.h (Jason Ekstrand)

i965 turns fddx/fddy into their coarse/fine variants based on the
ctx->Hint.FragmentShaderDerivative setting. It needs to know whether
this can impact a shader in order to better guess NOS settings.

I'd like to put this sort of metadata in the shader_info structure,
rather than adding more things to gl_program.

This will allow us to easily skip them when writting the struct

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.

It feels weird using GL_* enums in a Vulkan driver.

The vertex order is either clockwise or counterclockwise. We can just
store a "ccw" boolean rather than GLenum values. I don't want to use
GLenums in a Vulkan driver, and even in GL a simple boolean works fine.

This will be used in api_validate.c in a following patch when we
switch to using gl_program pointers for the pipelines CurrentProgram

This will allow us to simplify the current program logic for SSO.
Also since we aim to detach shader_info from nir_shader this will come
in handy avoiding passing nir_shader around just to keep track of
the stage we are dealing with.
V2: set stage for arb asm programs also.

This function is added here to ease refactoring towards using the new shared
shader_info. Once refactoring is complete and values are set directly it
will be removed.
We call it from _mesa_copy_linked_program_data() rather than glsl_to_nir()
so that the values will be set for all drivers. In order to do this some
calls need to be moved around so that we make sure to call
do_set_program_inouts() before _mesa_copy_linked_program_data()

This will allow use to stop copying values between structs and
will also simplify handling handling these values in the shader cache.
