i965/debug: Use the ull specifier for DEBUG enum defines

The INTEL_DEBUG variable is a uint64_t and if we want a enum value higer
than 32 bits, you need to use ull.  We might as well use it for all of them.

i965: Disallow linear blits that are not cacheline aligned.

The BLT engine on Gen8+ requires linear surfaces to be cacheline
aligned.  This restriction was added as part of converting the BLT to
use 48-bit addressing.

The main user, intel_emit_linear_blit, now handles this properly.
But we might also have linear miptrees; just refuse to blit those.

i965: Make intel_emit_linear_blit handle Gen8+ alignment restrictions.

The BLT engine on Gen8+ requires linear surfaces to be cacheline
aligned.  This restriction was added as part of converting the BLT to
use 48-bit addressing.

intel_emit_linear_blit needs to handle blits that are not cacheline
aligned, as we use it for arbitrary glBufferSubData calls and subrange
mappings.

Since intel_emit_linear_blit uses 1 byte per pixel, we can use the src/dst
pixel X offset field to represent the unaligned portion, and subtract
that from the address so it's cacheline aligned.

draw: fix prim ids when there's no gs

We were resetting the prim id count for each run of the prim assembler,
hence this only worked when the draw calls were very small (the exact limit
depending on the vertex size), since larger draw calls get split up.
So, do the same as we do already if there's a gs, reset it to zero explicitly
for every new instance (this possibly could use the same variable but that
isn't doable without some heavy refactoring and I'm not sure it makes sense).

nir/lower_source_mods: Don't propagate register sources

The nir_lower_source_mods pass does a weak form of copy propagation to
