Except for the deleted linux-cell target, these were just the target
cc/cflags. The only usage was for gen_matypes, which wants the
target's structure packing, not the host, anyway.

Every place that uses ASM_FLAGS already uses DEFINES. Not including
it in DEFINES is just a way to screw up potential users, as I've done
several times while working on the build system.

Even pre-automake, we rely on gmake features for pattern
substitutions, and replacing those with reams more make code is not
interesting. This will let us turn the old Makefiles using pattern
substitutions into automake without spewing warnings.

1) We need to insert a barrier between consecutive transform feedback calls.
2) VBO cache needs to be flushed when TFB output is used as VBO draw input.
Fixes Piglit test EXT_transform_feedback/immediate-reuse.
Thanks to Christoph Bumiller for pointing out bugs in previous versions
of this patch.

gl_ClipDistance needs special treatment in form of lowering pass
which transforms gl_ClipDistance representation from float[] to
vec4[]. There are 2 implementations - at glsl linker level (enabled
by LowerClipDistance option) and at glsl_to_tgsi level (enabled
unconditionally for gallium drivers). Second implementation is
incomplete - it does not take into account transform feedback (see
commit 642e5b413e0890b2070ba78fde42db381eaf02e5 "mesa: Fix transform
feedback of unsubscripted gl_ClipDistance array" for details).
There are 2 possible fixes:
- adding transform feedback support into glsl_to_tgsi version
- ripping gl_ClipDistance support from glsl_to_tgsi and enabling
gl_ClipDistance lowering on glsl linker side
This patch implements 2nd option. All it does is:
- reverts most of the commit 59be691638200797583bce39a83f641d30d97492
"st/mesa: add support for gl_ClipDistance"
- changes LowerClipDistance to true
Fixes Piglit tests "EXT_transform_feedback/builtin-varyings
gl_ClipDistance[{2,3,4,5,6,7,8}]-no-subscript" at least on nv50
and evergreen cards.

From the GL 3.0 spec (p.116):
"Multisample rasterization is enabled or disabled by calling
Enable or Disable with the symbolic constant MULTISAMPLE."
Elsewhere in the spec, where multisample rasterization is described
(sections 3.4.3, 3.5.4, and 3.6.6), the following text is consistently
used:
"If MULTISAMPLE is enabled, and the value of SAMPLE_BUFFERS is
one, then..."
So, in other words, disabling GL_MULTISAMPLE should prevent
multisample rasterization from occurring, even if the draw framebuffer
is multisampled. This patch implements that behaviour by setting the
WM and SF stage's "multisample rasterization mode" to
MSRAST_ON_PATTERN only when the draw framebuffer is multisampled *and*
GL_MULTISAMPLE is enabled.
Fixes piglit test spec/EXT_framebuffer_multisample/enable-flag.

Due to hardware limitations, MSAA is unsupported on Gen6 for formats
containing >64 bits of data per pixel. From the Sandy Bridge PRM,
vol4 part1, p72 ("Surface Format"):
If Number of Multisamples is set to a value other than
MULTISAMPLECOUNT_1, this field cannot be set to the following
formats:
- any format with greater than 64 bits per element
- any compressed texture format (BC*)
- any YCRCB* format
Gen7 has a similar, but less stringent limitation: formats with >64
bits of data per pixel only support 4x MSAA.
This patch causes the unsupported formats to report
GL_FRAMEBUFFER_UNSUPPORTED.
Fixes piglit "multisample-formats" tests on Gen6.

The system array values concept doesn't really because it expects the
system values to be fixed per call, which is wrong for gl_VertexID and
iffy for gl_SampleID. So this patch does two things:
- kill the array, have emit_fetch_system_value directly pick the
values it needs (only gl_InstanceID for now, as the previous code)
- correctly handle the expected type in emit_fetch_system_value

The idea here is to rewrite comparisons like 2 >= x with x <= 2; we want
to simply exchange arguments, not negate the condition. If equality was
part of the original comparison, it should remain part of the swapped
version.
This is the true cause of bug #50298. It didn't manifest itself on
Sandybridge because we embed the conditional modifier in the IF
instruction rather than emitting a CMP. All other platforms use CMP.
It also didn't manifest itself on the master branch because commit
be5f27a84d ("glsl: Refine the loop instruction counting.") papered over
the problem.
NOTE: This is a candidate for stable release branches.

This is failing sometimes, probably because TargetData keeps a structure layout
cache, which can becomes bogus, ever since the InvalidateStructLayoutInfo API
was removed in LLVM r135245.
This change merely makes the problem easier to diagnose (an assertion
failure instead of a random crash).

This allows drivers not to do any allocation in AllocStorage if the storage
cannot be allocated because of an unsupported internalformat + samples combo.
The little ugliness is that AllocStorage is expected to return TRUE in this
