The hardware supports zero stride just fine. This is a port
of 2af8a19831 from r300g.
NOTE: This is a candidate for both the 7.9 and 7.10 branches.

The RS690 memory controller prefers things to be on a different
boundary than the discrete GPUs, we had an attempt to fix this,
but it still failed, this consolidates the stride calculation
into one place and removes the really special case check.
This fixes gnome-shell and 16 piglit tests on my rs690 system.

tgsi_helper_copy is used on several occasions to copy a temporary result
into the real destination register to emulate writemasks for OP3 and
reduction operations. According to R600 ISA that's unnecessary.
This patch fixes this use for MAD, CMP and DP4.
When the driver is the last reference to libEGL.so, unloading it will
cause libEGL.so to be unmapped and give problems. Disable the unloading
for now. Still have to figure out the right timing to unload drivers.
The hardware apparently does support a zero stride, so let's use it.
This fixes missing objects in ETQW, but might also fix a ton of other
similar-looking bugs.

If a source operand has a non-native swizzle (e.g. the KIL instruction
cannot have a swizzle other than .xyzw), the lowering pass uses one or more
MOV instructions to move the operand to an intermediate temporary with
native swizzles.
This commit fixes that the presubtract information was lost during
the lowering.

This fixes broken rendering of trees in ETQW. The trees still disappear
for an unknown reason when they are close.
Broken since:
2ff9d4474b
r300/compiler: make lowering passes possibly use up to two less temps
NOTE: This is a candidate for the 7.10 branch.
do_assignment may apply implicit conversions to coerce the base type
of initializer to the base type of the variable being declared. Fixes
piglit test glsl-implicit-conversion-02 (bugzilla #32287). This
probably also fixes bugzilla #32273.
NOTE: This is a candidate for the 7.9 branch and the 7.10 branch.
There are exceptions to the table for depth texturing or rendering to
not-quite-supported formats thanks to the non-orthogonal component
selection for surface formats, but it's still a lot simpler.
Fixes piglit valgrind glsl-array-bounds-04 failure (FDO bug 29946).
NOTE:
This is a candidate for the 7.10 branch.
This is a candidate for the 7.9 branch.
The current state is allowed to be undefined past DrawElements et al.
Consequently omit that copying at least in the display list code.
This pays us some percents performance.

assert(current_save_state < MAX_META_OPS_DEPTH) did not compile.
Rename current_save_state to SaveStackDepth to be more consistent with
the style of the other fields.
VS places color attributes together so that SF unit can fetch the right
attribute according to object orientation. This fixes light issue in
mesa demo geartrain, projtex.
_mesa_meta_CopyPixels results in nested meta operations on Sandybridge.
Previoulsy the second meta operation overrides all states saved by the
first meta function.
When the application is not linked to any libGL*.so, loading st_GL.so
would give
/usr/local/lib/egl/st_GL.so: undefined symbol: _glapi_tls_Context
In that case, load libGL.so and try again. This works because
util_dl_open loads with RTLD_GLOBAL.
Fix "clear" OpenGL ES 1.1 demo.
Fixes piglit glx-shader-sharing crash.
When shaders are shared by multiple contexts, the shader's draw context
pointer may point to a previously destroyed context. Dereferencing the
context pointer will lead to a crash.
In this case, simply removing the flushing code avoids the crash (the
exec and sse shader paths don't flush here either).
There's a deeper issue here, however, that needs examination. Shaders
should not keep pointers to contexts since contexts might get destroyed
at any time.
NOTE: This is a candidate for the 7.10 branch (after this has been
tested for a while).
