tgsi: remove unneeded File == TGSI_FILE_INPUT test

We're already in an "if (File == TGSI_FILE_INPUT)" block at that point.
draw: fix front face injection

Inject front face only if the fragment shader uses it and
propagate through all channels because otherwise we'll
need to figure out the exact swizzle that the fs expects and
it's just simpler to make sure all the components within
the front face register are correctly set.

draw: implement proper primitive assembler as a pipeline stage

we used to have a face primitive assembler that we ran after if
the gs was missing but we had adjacency primitives in the pipeline,
lets convert it to a pipeline stage, which allows us to use it
to inject outputs (primitive id) into the vertices. it's also
a lot cleaner because the decomposition is already handled for us.

draw: add back separate input assembler

the issue is that stream output is run before the pipeline, which
means that unless we decompose the primitives before the so
then things crash. we could convert the entire stream output
code into a pipeline stage but it will take a bit, so for now
fix the crashes by simply re-adding the old input assembler
which is run before the SO.

mesa: Treat glBindFramebuffer and glBindFramebufferEXT more correctly

Allow user-generated names for glBindFramebufferEXT on desktop GL.
Disallow its use altogether for core profiles.

Names bound with glBindFramebuffer in desktop OpenGL are still
(incorrectly) shared across the share group instead of being
per-context.  This gets us a bit closer to being strictly conformant.
