This was a work-around to allow linking a program with only a fragment
shader in a GLES context. Now that we have GL_EXT_separate_shader_objects
in GLES contexts, we can just use that.

I don't know of any applications that actually use it. Now that Mesa
supports GL_ARB_separate_shader_objects in all drivers, this extension
is just cruft.
The entrypoints for the extension remain in the XML. This is done so
that a new libGL will continue to provide dispatch support for old
drivers that try to expose this extension.
Future patches will add OpenGL ES GL_EXT_separate_shader_objects, but
that's a different thing.

This will be used for GL_ARB_separate_shader_objects. That extension
not only allows separable shaders to rendezvous by location, but it also
allows traditionally linked shaders to rendezvous by location. The spec
says:
36. How does the behavior of input/output interface matching differ
between separable programs and non-separable programs?
RESOLVED: The rules for matching individual variables or block
members between stages are identical for separable and
non-separable programs, with one exception -- matching variables
of different type with the same location, as discussed in issue
34, applies only to separable programs.
However, the ability to enforce matching requirements differs
between program types. In non-separable programs, both sides of
an interface are contained in the same linked program. In this
case, if the linker detects a mismatch, it will generate a link
error.
v2: Make sure consumer_inputs_with_locations is initialized when
consumer is NULL. Noticed by Chia-I.
v3: Rebase on removal of ir_variable::user_location.
v4: Replace a (stale) FINISHME with some good explanation comments from
Eric.

When linking a separable program that contains only a fragment shader,
the producer will be NULL. Similar cases will exist with geometry
shaders and, eventually, tessellation shaders.

While writing the link_varyings::single_interface_input test, I
discovered that populate_consumer_input_sets assumes that all shader
interface blocks have been lowered to discrete variables. Since there
is a pass that does this, it is a reasonable assumption. It was,
however, non-obvious. Make the code fail when it encounters such a
thing, and add a test to verify that behavior.

Four initial tests:
* Create an IR list with a single input variable and verify that
variable is the only thing in the hash tables.
* Same as the previous test, but use a built-in variable
(gl_ClipDistance) with an explicit location set.
* Create an IR list with a single input variable from an interface block
and verify that variable is the only thing in the hash tables.
* Create an IR list with a single input variable and a single input
variable from an interface block. Verify that each is the only thing
in the proper hash tables.

I want to make some changes to this code, but first I want to make some
unit tests for it... so that I can capture the pre- and
post-invariants. Pulling the code out into its own function in a
non-anonymous namespace enables that.

This code was broken in some odd ways before. Too much state was being
saved, it was being restored in the wrong order, and in the wrong way.
The biggest problem was that the pipeline object was restored before
restoring the programs attached to the default pipeline.
Fixes a regression in the glean texgen test.
v3: Fairly significant re-write. I think it's much cleaner now, and it
avoids a bug with some meta ops that use shaders (reported by Chia-I).
v4: Check Pipeline.Current against NULL instead of Pipeline.Default.
