i965/sched: Change the scheduling heuristics to favor early program termination.

This uses the unblocked time of the exit assigned to each available
node to attempt to unblock exit nodes as early as possible,
potentially reducing the runtime of the shader when an exit branch is
taken.  There is a natural trade-off between terminating the program
as early as possible and reducing the worst-case latency of the
program as a whole (since this will typically move exit-unblocking
nodes closer to its dependencies potentially causing additional stalls
of the execution pipeline), but in practice the bandwidth and ALU
cycle savings from terminating the program earlier tend to outweigh
the slight increase in worst-case program execution latency, so it
makes sense to prefer nodes likely to unblock an earlier exit
regardless of the latency benefits of other available nodes.

I haven't observed any benchmark regressions from this change after
testing on VLV, HSW, BDW, BSW and SKL.  The FPS of the GfxBench
Manhattan benchmark increases by 10%-20% and the FPS of Unigine Valley
improves by roughly 5% depending on the platform and settings.

The change to the register pressure-sensitive heuristic is rather
conservative and gives precedence to the existing heuristic in order
to avoid increasing register pressure and causing spill count and SIMD
width regressions in shader-db.  It may make sense to revisit this

the discard condition is uniform across all channels of the SIMD8-16

executed for *all* channels if only one of the channels hadn't taken
the discard branch, potentially increasing the bandwidth and ALU usage
of the program unnecessarily.

This change increases the FPS by over 3x of a simple micro-benchmark

Note that we could potentially be more aggressive and use the NORMAL
predicate to discard individual channels, but that would need to
happen post-scheduling because the scheduler currently doesn't care to
reorder HALT instructions with respect to other instructions, and the

computations to become undefined -- If the scheduler didn't reorder
HALT instructions it would actually be safe to switch to NORMAL

Since the dawn of time, blorp has used offsets directly to get at different
mip levels and array slices of surfaces.  This isn't really necessary since
we can just use the base level/layer provided in the surface state.  While
it may have simplified blorp's original design, we haven't been using the
blorp path for surface state on gen8 thanks to render compression and
there's really no good need for it most of the time.  This commit restricts
such surface munging to the cases of fake W-tiling and fake interleaved
multisampling.
