The output of v_cmp instructions is s1 (a single SGPR) in wave32 mode,
as opposed to s2 (an SGPR-pair) in wave64 mode.
A couple of cases where this should have been fixed were omitted from
the previous patch by mistake.

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.

Prevents invalid code from being emitted for ROR/ROL instructions in
SIMD32 shaders.
The problem can be reproduced with the following tests while forcing
SIMD32 to be used for fragment shaders:
piglit.shaders.glsl-rotate-left
piglit.shaders.glsl-rotate-right
However the issue could occur in production already with compute
shaders and a workgroup size large enough to trigger SIMD32 dispatch.

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'
conformance tests on soft fp64 hardware with large enough subgroup
size (>16).
