If we have a d24x8 format, there is no stencil. Therefore, we can always
clear these bits too, which means this will be some kind of memset rather
than read-modify-write.
This is good for some 7% increase or so in gears with huge window size -
seems to have a bigger effect if things aren't in caches. Of course, any
real app won't spend nearly as much time comparatively in clearing
depth buffer in the first place, so the speedup will be much lower.

Fixes a number of GLES31 CTS failures and hangs on various hardware:

ES31-CTS.texture_gather.offset-gather-depth-2d

ES31-CTS.compute_shader.resources-texture
Some of them were actually passing by luck on some generations even
though we weren't uploading sampler state tables explicitly for the
compute stage, most likely because they relied on the cached sampler
state left from previous rendering to be close enough.

I have a patch that writes shaders as .shader_test files, and it uses
this function to create the headers (i.e. [vertex shader]).
[tess ctrl shader] isn't a valid shader_runner header - it's spelled

Even if re-linking fails rendering shouldn't fail as the previous
succesfully linked program will still be available. It also shouldn't
be possible to have an unlinked program as part of the current rendering
state.
This fixes a subtest in:
ES31-CTS.sepshaderobjs.StateInteraction
This change should improve performance on CPU limited benchmarks as noted
in commit d6c6b186cf.
>From Section 7.3 (Program Objects) of the OpenGL 4.5 spec:
"If a program object that is active for any shader stage is re-linked
unsuccessfully, the link status will be set to FALSE, but any existing
executables and associated state will remain part of the current rendering
state until a subsequent call to UseProgram, UseProgramStages, or
BindProgramPipeline removes them from use. If such a program is attached to
any program pipeline object, the existing executables and associated state
will remain part of the program pipeline object until a subsequent call to
UseProgramStages removes them from use. An unsuccessfully linked program may
not be made part of the current rendering state by UseProgram or added to
program pipeline objects by UseProgramStages until it is successfully
re-linked."
"void UseProgram(uint program);
...
An INVALID_OPERATION error is generated if program has not been linked, or
was last linked unsuccessfully. The current rendering state is not modified."

The parser was already failing correctly when the extension is

qualifier was still causing this to fail when available as both
cases share the same function for merging.
Here we add a parameter to differentiate between the two uses
and apply it to the duplicate test.

The whole point of inlining sources is to reduce loads. We can end up in
a situation where one value is used a lot of times, and one value is
used only once per instruction. The once-per-instruction one is the one
that should get inlined, but with the previous algorithm, it was given
no preference.
This flips things around to preferring putting less-referenced values
into src1 which increases the likelihood of them being inlined.
While we're at it, adjust the heuristic to not treat 0 as an immediate,
as well as (effectively) check for situations where LIMMs can't be
loaded. All this yields improvements on nvc0:
total instructions in shared programs : 6261157 -> 6255985 (-0.08%)
total gprs used in shared programs : 945082 -> 943417 (-0.18%)
total local used in shared programs : 30372 -> 30288 (-0.28%)
total bytes used in shared programs : 50089256 -> 50047880 (-0.08%)
local gpr inst bytes
helped 21 822 3332 3332
hurt 0 278 565 565
And more importantly avoids generating really bad code with SSBOs, where
we end up checking a lot of different values (usually immediates) against
the length.
On nv50 we get comparable results, and even improve packing (bytes went
down more than instructions):
total instructions in shared programs : 6346564 -> 6341277 (-0.08%)
total gprs used in shared programs : 728719 -> 725131 (-0.49%)
total local used in shared programs : 3552 -> 3552 (0.00%)
