The docs say it can be set for direct texture lookups, but even that
causes problems.
This fixes the wireframe bug:
https://bugs.freedesktop.org/show_bug.cgi?id=32688
NOTE: This is a candidate for the 7.9 and 7.10 branches.

Swizzles are now defined everywhere as a field with 12 bits that contains
4 channels worth of meaningful information. Any channel that is unused is
set to RC_SWIZZLE_UNUSED. This change is necessary because rgb instructions
and alpha instructions were initializing channels that would never be used
(channel 3 for rgb and channels 1-3 for alpha) with 0 (aka RC_SWIZZLE_X).
This made it impossible to use generic helper functions for swizzles,
because sometimes a channel value of 0 meant unused and other times it
meant RC_SWIZZLE_X.
All hacks that tried to guess how many channels were relevant have
also been removed.

This fixes an invalid "Too many hardware temporaries used" error in the
case where a source reads from a temporary register with an index greater
than max_temp_regs and then the source is marked as unused before the
register allocation pass.
NOTE: This is a candidate for the 7.9 branch.

Use rc_pair_ prefix for all pair instruction structs
Create a named struct for pair instruction args
Replace structs radeon_pair_instruction_{rgb,alpha} with struct
radeon_pair_sub_instruction. These two structs were nearly identical
and were creating a lot of cut and paste code. These changes are the
first step towards removing some of that code.

The r300 compiler can now emit instructions that select from the presubtract
source. A peephole optimization has been added to convert instructions like:
ADD Temp[0].x, none.1, -Temp[1].x into the INV (1 - src0) presubtract
operation.

This cleans up the mess in r3xx_compile_fragment_program.

The BGNLOOP and ENDLOOP instructions are now being used correctly, which
makes break and continue possible. The deadcode pass has been modified to
handle breaks, and the compiler is more careful about which loops are
unrolled.

Fixes fallout from 9a1bf52c.

This maybe breaks the vert compiler. Hopefully not.

In particular, this removes the dependency on prog_instruction, which
unfortunately creates some code duplication, but also opens a path towards
adding some hardware-specific things in there.

The field is not used, and in any case it would be more interesting to
manipulate from *outside* the compiler if we ever wanted to load several
fragment programs at the same time or something.

Also, this makes radeon_program_pair depend on the r300 fragment program
compiler. Since we now know that r600+ no longer use the same pairing
style in their ALU, we can stop pretending that program_pair is useful
for anything but r300-r500 fragment programs.

Adding constants is used in a number of non-native instruction
rewrites, and it required us to keep copies of modified gl_programs
around. This is a first step towards ending this.

The goal is to convert both Mesa and TGSI programs into an intermediate format
that happens to be convenient for us.

This is to prepare more experimentation and possible internal changes in the
compiler.

This is in preparation of sharing the fragment program compiler with Gallium:
Compiler code is moved into its own directory and modified so that it no
longer depends on driver structures.
