This allows drivers more freedom in how exactly they want to lower I/O,
e.g. first lowering I/O to temporaries.

We have to mark the additional shader input as used, otherwise it will
be eliminated, and we have to setup its index correctly.
This is a bit of a hack, but so is everything surrounding edgeflag
passthrough.

This will help allow us to simplify the handling of samplers by
storing them in a single location rather than duplicating them in
both gl_linked_shader and gl_program.

This will allow us to directly store metadata we want to retain in
gl_program this metadata is currently stored in gl_linked_shader and
will be lost if relinking fails even though the program will remain
in use and is still valid according to the spec.
"If a program object that is active for any shader stage is re-linked
unsuccessfully, the link status will be set to FALSE, but any existing
executables and associated state will remain part of the current
rendering state until a subsequent call to UseProgram,
UseProgramStages, or BindProgramPipeline removes them from use."
This change will also help avoid the double handing that happens in
_mesa_copy_linked_program_data().

In i965 we were calling _mesa_reference_program() after creating
gl_program and then later calling it again with NULL as a param
to get the refcount back down to 1. This changes things to not
use _mesa_reference_program() at all and just have gl_linked_shader
take ownership of gl_program since refcount starts at 1.
The st and ir_to_mesa linkers were worse as they were both getting
in a state were the refcount would never get to 0 and we would leak
the program.

As of 59864e8e02 we just use the location assigned by the front-end and
no longer need this for i965.
Since there were some issues in the logic with assigning arrays the same
driver location if they didn't start at the same location just remove it
and let other drivers implement a solution if needed when they add
ARB_enhanced_layouts support.

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 allows us to do some small tidy ups, but will also allow us to call
a new function that copies values to a shared shader info from here.
In order to make this change this function now requires
_mesa_reference_program() to have previously been called.

probably not leave them as vertex inputs with a driver_location that

There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.
The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.
We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

Instead use the internal gl_shader_stage enum everywhere. This
makes things more consistent and gets rid of unnecessary
conversions.
Ideally it would be nice to remove the Type field from gl_shader
altogether but currently it is used to differentiate between
gl_shader and gl_shader_program in the ShaderObjects hash table.
