The previous commit removed the name_as_gs_input from add_varying, so
the macro is unnecessary.

nvc0: keep track of cb bindings per buffer, use for upload settings

CB updates to bound buffers need to go through the CB_DATA endpoints,
otherwise the shader may not notice that the updates happened.
Furthermore, these updates have to go in to the same address as the
bound buffer, otherwise, again, the shader may not notice updates.

So we keep track of all the places where a constbuf is bound, and
iterate over all of them when updating data. If a binding is found that
encompasses the region to be updated, then we use the settings of that
binding for the upload. Otherwise we upload as a regular data update.

This fixes piglit 'arb_uniform_buffer_object-rendering offset' as well
as blurriness in Witcher2.

i965: Disallow PixelTransfer operations for tiled-memcpy TexImage/ReadPixels

The tiled memcpy fast paths perform a simple blit (with only a couple of
trivial pixel conversion routines) and do not accommodate PixelTransfer
operations. Therefore if any are set, fallback to the regular routines.
Note that PixelTransfer only applies to TexImage and ReadPixels, not to
GetTexImage.

i965/vec4: Don't unspill the same register in consecutive instructions

If we have spilled/unspilled a register in the current instruction, avoid
emitting unspills for the same register in the same instruction or consecutive
instructions following the current one as long as they keep reading the spilled
register. This should allow us to avoid emitting costy unspills that come with
little benefit to register allocation.

v2:
  - Apply the same logic when evaluating spilling costs (Curro).

v3:
  - Abstract the logic that decides if a register can be reused in a function.
    that can be used from both spill_reg and evaluate_spill_costs (Curro).

v4:
  - Do not disallow reusing scratch_reg in predicated reads (Curro).
  - Track if previous sources in the same instruction read scratch_reg (Curro).
  - Return prev_inst_read_scratch_reg at the end (Curro).
  - No need to explicitily skip scratch read/write opcodes in spill_reg (Curro).
  - Fix the comments explaining what happens when we hit an instruction that
    does not read or write scratch_reg (Curro)
  - Return true early when the current or previous instructions read
    scratch_reg with a compatible mask.

v5:
  - Do not return true early, the loop should not be expensive anyway
    and this adds more complexity (Curro).

Before we set a single bit to tell the FS whether or not we'll be using an input
coverage mask. Now we have some options which are implementing various
extensions. These bits are used for the various conservative rasterization
mechanisms (for collision detection, binning, and whatever else).

I believe that the behavior is preserved because the problem which conservative
rasterization is attempting to fix would go away with the "NORMAL" mode (at the
cost of performance, I believe).

This patch serves as documentation of the change by creating the enums, as well
as giving some of the history with the links here so that the next person who
comes along and looks at it doesn't spend as long as I had to in order to

Previously, this algorithm had been done in software, and this can still be used
as long as we don't export an extension stating otherwise.
