glsl: fix glsl optimization infinite loop from copy_propagation_elements

The trick was to produce an assignment in the IR along the lines of:

      (assign  (xyzw) (var_ref R0)  (swiz wwww (var_ref R0) ))

which occurs only rarely even in code that looks like it should do
this, because of the assignment temporaries generated in ast_to_hir.

From the IR above, this optimization pass would then propagate
references of R0 into R0.wwww (seems reasonable), but without this
patch, a later reference of R0.wwww would see R0 first, turning that
into R0.wwww.wwww, which triggered opt_swizzle_swizzle, and then we
looped back to this code to do it again.  Avoid that by skipping over
the usual ir_rvalue visitor's ir_swizzle hook, so that we get
handle_rvalue() on the ir_swizzle itself, not its referenced value.
Looking at only the swizzle will always optimize away at least as much
as looking at the swizzle's refererenced value.

We now still claim to propagate r0.w into r0.w, but at least we don't
trigger the loop.

mesa: rework ctx->Driver.CopyTexSubImage() parameters

Replace target, level parameters with gl_texture_image.
Add gl_renderbuffer parameter to indicate source buffer for the copy.

This removes some redundant code in the drivers to find the source
renderbuffer and the destination texture image (which we already had
in _mesa_CopyTexSubImage).
