b4f585665c glsl: Mark the array access for whole-array comparisons. 
By not doing so, the uniform contents of
glsl-uniform-non-uniform-array-compare.shader_test was getting thrown
out since nobody was recorded as dereferencing the array.

f361f8a8a9 i965: Add support for loops in the VS. 
This follows the changes done for the FS alongside the EU emit code.

251d15d888 i965: Enable IF statements in the VS. 
While the actual IF instructions were fixed by Zhenyu, we were still
flattening them to conditional moves.

843a6a308e i965: Add support for gen6 CONTINUE instruction emit. 
At this point, piglit tests for fragment shader loops are working.

00e5a743e2 i965: Add support for gen6 BREAK ISA emit. 
There are now two targets: the hop-to-end-of-block target, and the
target for where to resume execution for active channels.

4890e0f09c i965: Add support for gen6 DO/WHILE ISA emit. 
There's no more DO since there's no more mask stack, and WHILE has
been shuffled like IF was.

fcf6b353bf r300g: disable ARB_texture_swizzle if S3TC is enabled on r3xx-only 
r3xx cannot swizzle compressed textures. r4xx+ is unaffected.

NOTE: This is a candidate for the 7.9 branch.

d2d7a273c5 glsl: Add comments to lower_jumps (from the commit message). 
This is essentially Luca's commit message, but placed at the top of the
file.

1802cb9baf glsl: Remove "discard" support from lower_jumps. 
The new lower_discard and opt_discard_simplification passes should
handle all the necessary transformations, so lower_jumps doesn't need to
support it.

Also, lower_jumps incorrectly handled conditional discards - it would
unconditionally truncate all code after the discard.  Rather than fixing
the bug, simply remove the code.

NOTE: This is a candidate for the 7.9 branch.

940df10100 glsl: Add a lowering pass to move discards out of if-statements. 
This should allow lower_if_to_cond_assign to work in the presence of
discards, fixing bug #31690 and likely #31983.

NOTE: This is a candidate for the 7.9 branch.

2ca9256911 r600c: fix some opcodes on evergreen

on evergreen.  arl still needs to be fixed on evergreen; see
r600g for reference.

c91c386012 st/vega: Create drawing surface mask as needed. 
As the blend texture, a drawing surface mask is used when masking is
enabled.  It should be created as needed.

b06de80843 st/vega: Fix paint coordinates transformations. 
Depending on whether vgDrawPath(mode), vgDrawImage, or vgDrawGlyph[s] is
called, different paint-to-user and user-to-surface matrices should be
used to derive the sample points for the paint.

This fixes "paint" demo.

213e288e78 st/vega: More flexible shader selection. 
Divide bits of VegaShaderType into 6 groups: paint, image, mask, fill,
premultiply, and bw.  Each group represents a stage.  At most one shader
from each group will be selected when constructing the final fragment
shader.

5d64a06a63 st/vega: Add primitive text support. 
Optional features such as auth-hinting are not implemented.  There is no
anti-aliasing, and no effort is done to keep the glyph origin integral.
So the text quality is poor.
