Per the semi-recently-released NVIDIA docs, when this bit is not
enabled, then the result for RT[0] will be used. So if e.g. only a
single RT is drawn to and it's not RT[2], the results will not be
visible. Fixes
GTF-GL45.gtf33.GL3Tests.explicit_attrib_location.explicit_attrib_location_pipeline
which was failing due to a frag shader outputting only to location=2.

This corresponds to gl_PrimitiveID and gl_Layer. When both of these are
stored in a single AST.64 or AST.128 operation, then it appears as
though the whole store fails. Fixes the recently extended

The fix was found by Karol Herbst a long time ago, but it was unclear
why it helped or if it would create additional problems. This change
adds a comment that explains what's going on, and in the process also
normalizes the nv50 implementation to match.
The coordinates which are fed to gl_Position map directly to pixel
coordinates, since the viewport transform is disabled. If the
framebuffer is MSAA, then that doesn't affect the pixel coordinates at
all, it's just that each pixel has multiple samples.
Note that this makes it really clear that this approach is inappropriate
for EXT_framebuffer_multisample_blit_scaled, and also the 3d path will
fail terribly for direct copies. Thankfully the 2d path normally takes
care of this.
Fixes KHR-GL43.packed_depth_stencil.blit.depth32f_stencil8 as well as
scaling issues in a number of EXT_framebuffer_multisample-related piglit
tests (although they continue to fail due to inaccuracies).

This will be convenient in a later commit enabling SIMD32 fragment
shaders, and happens to fix the calculation for MATH instructions
which is currently inaccurate for SIMD-lowered instructions on Gen4-5
platforms (all of them on Gen4 in SIMD16 mode), since it was based on
the shader's dispatch width rather than on the actual execution size
of the instruction.
This causes some shader-db noise on Gen4 due to the more compact
register allocation interacting with the SEND dependency workarounds,
but otherwise no major changes.

The liveness calculation done by the local CSE pass in order to prune
AEB entries whose sources are no longer live is currently inaccurate,
because the live intervals are calculated once at the beginning of the
pass, so they don't take into account any of the copy instructions
inserted by the CSE pass as it makes progress. However the IP counter
used in that calculation is based on the start_ip of the basic block,
which is updated automatically whenever any instructions are inserted
into the CFG. This causes the IP counter and liveness intervals to
get out of sync in programs with multiple basic blocks, causing the
CSE pass to toss AEB entries prematurely, which can lead to missed
optimization opportunities rather non-deterministically.
On BDW this leads to the following shader-db changes:
total instructions in shared programs: 14952488 -> 14951763 (-0.00%)
instructions in affected programs: 45416 -> 44691 (-1.60%)
helped: 40
HURT: 4
total spills in shared programs: 20989 -> 20970 (-0.09%)
spills in affected programs: 103 -> 84 (-18.45%)
helped: 3
HURT: 0
total fills in shared programs: 24981 -> 24926 (-0.22%)
fills in affected programs: 127 -> 72 (-43.31%)
helped: 3
HURT: 0
In addition it avoids a number of regressions in combination with some
of the optimization changes I'm working on for SIMD32, which would
have made CSE more effective... Causing it to be less effective
elsewhere in the program astonishingly.

The problem occured when the return payload of a SIMD8 SEND
instruction was re-used as source payload of an EOT SEND message. In
such cases the interference edge added by that workaround between the
payload and grf127_send_hack_node would have no effect, because the
payload would be allocated to a fixed range of registers containing
r127 by the special handling of EOT message payloads in the same
function. This would cause things to blow up if the source payload of
the first SIMD8 message ended up being allocated to a range which
happened to overlap the destination.
Fix it by avoiding r127 altogether in the allocation of EOT message
payloads.
The problem can be reproduced on ICL with the fp-indirections2 Piglit
test-case in combination with the other optimizer changes of this
series.

The current implementation was broken for any integers between 2^24
and 2^30 (it would return zero for me on ICL). The reason is that for
such integers we wouldn't take the 'if (0 <= shiftCount)' early return
path, however 'shiftCount + 7' would be positive, leading to a
negative 'count' argument passed to __shift64RightJamming(), which
would give undefined results.
This reworks the affected conversion functions to use either
__shortShift64Left() or __shift64RightJamming() based on the sign of
the final shift count, which should avoid the problem. In addition
this should qualify as a clean-up/optimization -- This implementation
of the conversion functions translates to 7 instructions less than the
original on Intel hardware.
This fixes the 'KHR-GL46.shader_ballot_tests.ShaderBallotFunctionBallot'

size (>16).
