From the GLSL 4.40 spec, section 6.4 (Jumps):

    The continue jump is used only in loops. It skips the remainder of
    the body of the inner most loop of which it is inside. For while

    previously defined.

Previously, we incorrectly treated a "continue" statement as jumping
to the top of a do-while loop.

This patch fixes the problem by replicating the loop condition when

i965/blorp: do not use unnecessary hw-blending support

This is really not needed as blorp blit programs already sample
XRGB normally and get alpha channel set to 1.0 automatically by
the sampler engine. This is simply copied directly to the payload
of the render target write message and hence there is no need for
any additional blending support from the pixel processing pipeline.

The blending formula is anyway broken for color components, it
multiplies the color component with itself (blend factor is the
component itself).
Alpha blending in turn would not fix the alpha to one independent
of the source but simply used the source alpha as is instead
(1.0 * src_alpha + 0.0 * dst_alpha).

Quoting Eric:

 "If we want to actually make the no-alpha-bits-present thing work,
  we need to override the bits in the surface state or in the
  generated code.  In the normal draw path, it's done for sampling
  by the swizzling code in brw_wm_surface_state.c, and the blending
  overrides is just to fix up the alpha blending stage which
  doesn't pay attention to that for the destination surface."

If one modifies piglit test gl-3.2-layered-rendering-blit to use
color component values other than zero or one, this change will
kick in on IVB. No regressions on IVB.

This is effectively revert of c0554141a9b831b4e614747104dcbbe0fe489b9d:

    i965/blorp: Support overriding destination alpha to 1.0.

    Currently, Blorp requires the source and destination formats to be
    equal.  However, we'd really like to be able to blit between XRGB and
    ARGB formats; our BLT engine paths have supported this for a long time.

    For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
    interpreted as 1.0.  For XRGB -> ARGB, we need to smash the alpha
    channel to 1.0 when writing the destination colors.  This is fairly
    straightforward with blending.

    For now, this code is never used, as the source and destination formats
    still must be equal.  The next patch will relax that restriction.

    NOTE: This is a candidate for the 9.1 branch.

freedreno/a3xx/compiler: new compiler

The new compiler generates a dependency graph of instructions, including
a few meta-instructions to handle PHI and preserve some extra
information needed for register assignment, etc.

The depth pass assigned a weight/depth to each node (based on sum of
instruction cycles of a given node and all it's dependent nodes), which
is used to schedule instructions.  The scheduling takes into account the
minimum number of cycles/slots between dependent instructions, etc.
Which was something that could not be handled properly with the original
compiler (which was more of a naive TGSI translator than an actual
compiler).

The register assignment is currently split out as a standalone pass.  I
expect that it will be replaced at some point, once I figure out what to
do about relative addressing (which is currently the only thing that
should cause fallback to old compiler).

There are a couple new debug options for FD_MESA_DEBUG env var:

  optmsgs - enable debug prints in optimizer
  optdump - dump instruction graph in .dot format, for example:

http://people.freedesktop.org/~robclark/a3xx/frag-0000.dot.png
http://people.freedesktop.org/~robclark/a3xx/frag-0000.dot

At this point, thanks to proper handling of instruction scheduling, the
new compiler fixes a lot of things that were broken before, and does not

mesa: Rename ElementArrayBufferObj to IndexBufferObj.

DirectX and most hardware documentation use the term "Index Buffer" to
refer to a buffer containing indexes into arrays of vertex data, which
allows random access to vertex data, rather than sequential access.

OpenGL uses a different term for this concept: "Element Array Buffer".
However, "Index Buffer" has become much more widespread.  A quick
Google search shows 29,300 hits for "Element Array Buffer" vs.
82,300 hits for "Index Buffer."

Arguably, "Index Buffer" is clearer: an "element of an array" (or list)
usually refers to an actual item stored in the array, not the index used
to refer to it.

The terminology is also already used in Mesa: some VBO module code for
dealing with ElementArrayBufferObj names local variables "ib".

i965: Update multisampling state for Broadwell.

On previous platforms, 3DSTATE_MULTISAMPLE contained the number of
samples, pixel location, and the positions of each sample within a pixel
for each multisampling mode (4x and 8x).  It was also a non-pipelined
command, presumably since changing the sample positions is fairly
drastic.

Broadwell improves upon this by splitting the sample positions out into
a separate non-pipelined state packet, 3DSTATE_SAMPLE_PATTERN.  With
that removed, 3DSTATE_MULTISAMPLE becomes a pipelined state packet.

Broadwell also supports 2x and 16x multisampling, in addition to the 4x
and 8x supported by Gen7.  This patch, however, does not implement 2x
and 16x.
