i965: Fix virtual_grf_interferes() between calculate_live_intervals() and DCE.
This fixes the blue zombies bug in l4d2.
NOTE: This is a candidate for the 9.0 branch.

i965/fs: Rename virtual_grf_next to virtual_grf_count.
"count" is a more useful name, since most of the time we're using it for
looping over the variables.

i965/fs: Remove the requirement of no dead code for interference checks.
This will be convenient when I want to comment out optimization code
to see the raw program being optimized, but more importantly will let
the interference check be used during optimization.

i965/fs: When doing no work for live interval calculation, do no allocation.
When I had a bug causing the backend to never finish optimizing, it
also sent me deep into swap. This avoids extra memory allocation per
trip through optimization, and thus may reduce the peak memory
allocation of the driver even in the success case.

i965: Convert live interval computation to using live variable analysis.
Our previous live interval analysis just said that anything in a loop
was live for the whole loop. If you had to spill a reg in a loop,
then we would consider the unspilled value live across the loop too,
so you never made progress by spilling. Eventually it would consider
everything in the loop unspillable and fail out.
With the new analysis, things completely deffed and used inside the
loop won't be marked live across the loop, so even if you
spill/unspill something that used to be live across the loop, you
reduce register pressure. But you usually don't even have to spill
any more, since our intervals are smaller than before.
This fixes assertion failure trying to compile the shader for the
"glyphy" text rasterier and piglit glsl-fs-unroll-explosion.
Improves Unigine Tropics performance 1.3% +/- 0.2% (n=5), by allowing
more shaders to be compiled in 16-wide mode.
