Unsigned long is 32bit on several platforms (e.g., Windows), yielding
1UL << 32 to be zero.
Note that BITFIELD64_BIT result is often assigned to variables of type
GLbitfield, instead of GLbitfield64. That's probably wrong and should be
addressed in a later change.
It should have been a tip when the spec says "However, implicitly
sized arrays cannot be assigned to. Note, this is a rare case that
*initializers and assignments appear to have different semantics*."

Fixes bugzilla #34367.
NOTE: This is a candidate for stable release branches.
Early Z support is set in the DST_VARS command. Hence split up static
state emission to avoid reissuing to much on fragment shader changes,
especially the costly dst buffer relocations.

The optimization loop won't reinsert noise instructions or quadop
vectors, so we were traversing the tree for nothing. Lowering vector
indexing was in the loop after do_common_optimization() to avoid the
work if it ended up that the index was actually constant, but that has
been called already in the core.
Most of the time we don't have a non-uniform struct variable in the
shader, so this cuts the time spent in do_structure_splitting during
glean texCombine by about 2/3.
This fixes an issue where the .obj files wound up in the src/
directory rather than the build/ directory. That prevented
combined 32-bit and 64-bit builds from working.

Additionally, to discarding the whole buffer, use
PIPE_TRANSFER_DISCARD_RANGE in pipe_buffer_write when the
write covers only part of the buffer.

In memory mapping buffer objects make use of
PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE and PIPE_TRANSFER_DISCARD_RANGE
when appropriate.

It doesn't support them. Also, we shouldn't be
emitting CB_BLENDx_CONTROL on R600 as the regs don't
exist there, but I'm not sure of the best way to deal
with this in the current r600 winsys.

This packet is required when updating the DB, CB,
or STRMOUT base addresses on rv6xx for the surface
sync logic to work correctly.

This sort of worked because blend state setup cleared MULTIWRITE_ENABLE again,
but that's not something we want to depend on.

Disable Z_EXPORT / STENCIL_EXPORT / KILL_ENABLE again if a shader doesn't
use those. This is similar to 0a6f09a76a.

The idea behind this is that anything touching registers should be in
r600_state.c or evergreen_state.c. This is also consistent with
evergreen_pipe_shader_vs().

We need more and more of these, and it is difficult and prone to version
incompatability issues trying to single out every one of them.
This mimicks what was done in SCons.
This enables the new shadow texture functions in GLSL 1.30.

The assignment on line 368, `tex_swizzles[i] = SWIZZLE_NOOP`, is rendered

This is necessary for GLSL 1.30+ shadow sampling functions, which return
a single float rather than splatting the value to a vec4 based on
GL_DEPTH_TEXTURE_MODE.
