00989d5bfc llvmpipe: Relax the colormask constraint on opaque. 
Also, include the color buffer in the key. Not having it there
causes a tight knots in the logic to determine when it is OK or not
to discard previous color buffer contents.

30c5d5d9d8 scons: Re-enable SSE on MinGW. 
It seems to be working correctly with gcc 4.4, and enabling it allows to
test some of the llvmpipe instrinsics on Windows.

9a3df46fbc ir_reader: Only validate IR when a global 'debug' flag is set. 
This extra validation is very useful when working on the built-ins, but
in general overkill - the results should stay the same unless the
built-ins or ir_validate have changed.

Also, validating all the built-in functions in every test case makes
piglit run unacceptably slow.

ece8490bb5 r300g,r300c: memset the compiler struct to zeros 
This should fix bogus reports "Too many temporaries." and maybe some others.

9fc50968ad nvfx: support using blitter to copy depth/stencil resources, fix Heaven 
We might want to copy them as color ones though.

Also works around crash in Unigine Heaven due to failing to allocate
a 64 MB temporary in GART for a CPU copy.

Unigine Heaven now works on nv40, albeit with very heavy glitches (with
the floating branch with render_hdr 0).

2e6c65722a nvfx: fix some subrectangle copies 
Actually, we may want to get rid of the x/y coordinates for linear
surfaces, and realign the origin from scratch if necessary, instead
of doing this "on-demand realignment".

280665be70 Revert "ir_to_mesa: Load all the STATE_VAR elements of a builtin uniform to a temp." 
This reverts commit 5ad74779ce.

Sorry, but I had to revert this.

Any commit which needlessly increases the number of temporaries is wrong.
More temporaries mean less shader performance because of reduced parallelism
and therefore less efficient latency hiding. In this case, there is possible
performance degradation of every shader which uses GL state variables.
I cannot accept this.

63943c8fcd r300/compiler: improve register allocation with indexable temporaries for VS

cfc461fca6 r300g: add a new debug option which disables compiler optimizations 
Those are:
- dead-code elimination
- constant folding
- peephole (mainly copy propagation)
- register allocation

There are some bugs which I need to track down.

Also fix up the descriptions of all the debug options.
