have two different unions for constants?  No good reason other than one of

vulkan/wsi/x11: Destroy Present event context when destroying swapchain

glsl: use linked_shaders bitmask to iterate stages for subroutine fields

This should be faster than looping over every stage and null checking, but
will also make the code a bit cleaner when we switch to getting more fields
from gl_program rather than from gl_linked_shader as we can just copy the
pointer and not need to worry about null checking then copying.

mesa: optimise interleaved sso validation

Now that we have a linked_stages bitfield we can use this

This change is also required to be able to use gl_program

mesa/glsl: add bitmask to track stages a program was linked against

This will be used to enable us to store the current gl_program
rather than gl_shader_program in the gl_pipline_object allowing
us to simplify handing of validation.

Also we should not be depending on _LinkedShader for this information
as it may contain shaders from a failed linking attempt rather than
the current program still in use.

We could also use this mask to iterate over the stages during linking
with _mesa_bit_scan() rather then the current method of NULL checking
each stage.
