This saves both register space and upload bandwidth for unused values.
Note that previously we were relying on the visitor not initially
generating references to different sets of uniforms between the 8-wide
and 16-wide code generation, and now we're relying on them dead-code
eliminating the same stuff, too.
We should remove the relocations which caused a validation failure
from the list, so that the kernel receives only the validated ones.

That code drops performance in Unigine Heaven and Tropics
by a factor of 10. That's too crazy even for a debug build.

Unlike C++, empty declarations such as
float;
should be valid. The spec is not explicit about this actually.
Some apps that generate their shader sources may rely on this. This was
noted when porting one of them to Linux from Windows.

Resolve via glBlitFramebuffer allows resolving a sub-region of a
renderbuffer to a different location in any mipmap level of some
other texture, and, with a new extension, even scaling. Therefore,
location and size parameters are needed.
The mask parameter was added because resolving only depth or only
stencil of a combined buffer is possible as well.
Full information about the blit operation allows the drivers to
take the most efficient path they possibly can.
This avoids the following runtime error with EGL on platforms that
require linking with libm for nontrivial math functions:
failed to load module: /xorg/lib64/gbm/gbm_gallium_drm.so: undefined

When we have two ENDIFs in a row, we shouldn't modify the pop_count
for the same alu clause twice.

Use backend_map kernel query if supported, otherwise analyze ZPASS_DONE
results to get the mask.
Fixes lockups with predicated rendering due to incorrect query buffer
initialization on some cards.

These looked more like copy-and-paste to me than the others (which
looked more like possibly someone forgot to write some code in a
refactor), so I didn't verify where they came from.
