subspan have the same derivative.  I considered SAMPLE_STATE too, which allows

glsl: Initialize all member variables of _mesa_glsl_parse_state on construction.

The _mesa_glsl_parse_state object relies on the memory allocator
zeroing out its contents before it's initialized, which is quite an
unusual practice in the C++ world because it ties objects to some
specific allocation scheme, and gives unpredictable results when an
object is created with a different allocator -- Stack allocation,
array allocation, or aggregation inside a different object are some of
the useful possibilities that come to my mind.  Initialize all fields
from the constructor and stop using the zeroing allocator.

control data header size/format appropriately for EndPrimitive()), I
incorrectly numbered the DWORDs in the 3DSTATE_GS command starting
from 1 instead of starting from 0.  This caused the control data

Use -Bsymbolic when linking libEGL.so

For some reason that I don't yet fully understand, Glaze does not work with
libEGL unless libEGL is linked with -Bsymbolic.[*]

Beyond that specific reason, all of the reasons for which libGL.so is linked
with -Bsymbolic, (see the commit history), should also apply here.

[*] The specific behavior I am seeing is that when Glaze calls dlopen for
libEGL.so, ifunc resolvers within Glaze for EGL functions are called before
the dlopen returns. These resolvers cannot succeed, as they need the return
value from dlopen in order to find the functions to resolve to. I don't know
what's causing these resolvers to be called, but I have verified that linking
libEGL with -Bsymbolic causes this problematic behavior to stop.

i965/blorp: retype destination register for texture SEND instruction to UW.

From the bspec documentation of the SEND instruction:

    "destination region cannot cross the 256-bit register boundary."

To avoid violating this restriction when executing SIMD16 texturing
operations (such as those used by blorp), we need to ensure that the
destination of the SEND instruction doesn't exceed 256 bits in size.
An easy way to do this is to set the type of the destination register
to UW (unsigned word), since 16 unsigned words can fit inside a
256-bit register.  Fortunately, this has no effect on the sampling
operation, since the sampler always infers the destination data type
from the sampler message rather than from the type of the instruction
operand.

Previously, we did this for texturing operations issued by the vec4
and fs back-ends, but not for blorp.  This patch makes blorp use the
same trick.

I haven't observed any behavioural difference on actual hardware due
to this patch, but it avoids a warning from the simulator so it seems
like the right thing to do.
