This should handle the new lod_zero modifier more correctly.
The runtime-conditional is a bit more complex however we now also do
scalar lod computation when appropriate which should more than make up for it.
The refactoring should also fix an issue with explicit lods
(lod clamp wasn't applied to them).
Also, always pass lod as the 5th element from tgsi executor, which simplifies
things (get rid of annoying conditionals later).
v2: based on Brian's feedback, use switch in a couple of places, fix up
some function parameter names, fix up comments.

There were several bugs how this was handled, most opcodes wouldn't even
have fetched the right arguments.
Also, the tex "target" is coming from the sampler view, hence it cannot
have information about shadow comparisons - fortunately this is not only
sampler state but also needs to have matching instruction, so just use this
instead to identify shadow comparisons.
Still untested (compiles...).
Note that sample_i and sviewinfo are still busted (just assert).
(The problem is that the interface for doing the opengl-equivalent functions
txf and txq is tied to the specific the sampler itself but these opcodes
have no sampler associated with them. Oops...)
Also, even the other sample instructions will not work correctly since
they always operate on samplers which include the texture state. Fixing
this wouldn't be that difficult but most likely make softpipe quite a bit
slower when using the OpenGL tex opcodes (as the samplers have pre-baked
function calls in the sampler state depending on texture state and that stuff
would need to be evaluated at runtime), so leave it for now.

Need to calculate the number of mip levels (if it would be worthwile could
store it in dynamic state).
While here, the query code also used chan 2 for the lod value.
This worked with mesa state tracker but it seems safer to use chan 0.
Still passes piglit textureSize (with some handwaving), though the non-GL
parts are (largely) untested.
v2: clarify and expect the sviewinfo opcode to return ints, not floats,
just like the OpenGL textureSize (dx10 supports dst modifiers with resinfo).
Also simplify some code.

This adds support of the additional blending factors to the blend function
itself, and also enables testing of it in lp_test_blend (which passes).
Still need to add the glue code of linking fs shader outputs to blend inputs
in llvmpipe, and probably need to add special handling if destination doesn't
include alpha (which lp_test_blend doesn't test).

Previous to this patch, there were 13 identical definitions of this
macro in Mesa source. That's ridiculous. This patch consolidates 6
of them to a single definition in src/mesa/main/macros.h.
Unfortunately, I wasn't able to eliminate the remaining definitions,
since they occur in places that don't include src/mesa/main/macros.h:
- include/pci_ids/pci_id_driver_map.h
- src/egl/drivers/dri2/egl_dri2.h
- src/egl/main/egldefines.h
- src/gbm/main/backend.c
- src/gbm/main/gbm.c
- src/glx/glxclient.h
- src/mapi/mapi/stub.c
I'm open to suggestions as to how to deal with the remaining redundancy.

Previously, the i965 driver enabled EXT_framebuffer_multisample even
on pre-gen6 chipsets. However, since we don't support multisampling
on these chips, we set GL_MAX_SAMPLES=1 (the minimum allowed by
EXT_framebuffer_multisample), and if the client ever requested a
multisample buffer, we quietly supplied them with a single-sampled
buffer instead.
After some discussion on the mailing list (see thread
"ext_framebuffer_multisample: check for num_samples<=1"), it's clear
that this was the wrong approach. The correct approach is to only
expose EXT_framebuffer_multisample when we truly support
multisampling; that frees us to set a sensible value of
GL_MAX_SAMPLES=0 on other chipsets, so that we never have to deal with
a client requesting a multisample buffer when multisampling isn't
supported.
This change causes the following piglit tests to be skipped on
chipsets prior to Gen6:
- "ARB_framebuffer_sRGB/blit {renderbuffer,texture}
{linear,linear_to_srgb,srgb,srgb_to_linear}
{downsample,msaa,upsample} {disabled,enabled}"
- EXT_framebuffer_multisample/blit-mismatched-formats
- EXT_framebuffer_multisample/blit-mismatched-sizes
- EXT_framebuffer_multisample/dlist
- EXT_framebuffer_multisample/interpolation 0 *
- EXT_framebuffer_multisample/minmax
- EXT_framebuffer_multisample/negative-copypixels
- EXT_framebuffer_multisample/negative-copyteximage
- EXT_framebuffer_multisample/negative-max-samples
- EXT_framebuffer_multisample/negative-mismatched-samples
- EXT_framebuffer_multisample/negative-readpixels
- EXT_framebuffer_multisample/renderbuffer-samples
- EXT_framebuffer_multisample/renderbufferstorage-samples
- EXT_framebuffer_multisample/samples
This is expected, since the above tests exercise MSAA functionality,
and shouldn't be run on systems prior to Gen6.

Previously the loop_state was allocated in the loop_analysis
constructor, but not freed in the (nonexistent) destructor. Moving
the allocation of the loop_state makes this code appear less sketchy.
Either way, there is no actual leak. The loop_state is freed by the
single caller of analyze_loop_variables.

In the documentation for BindBufferRange, OpenGL specs from 3.0
through 4.1 contain this language:
"The error INVALID_VALUE is generated if size is less than or
equal to zero or if offset + size is greater than the value of
BUFFER_SIZE."
This text was dropped from OpenGL 4.2, and it does not appear in the
GLES 3.0 spec.
Presumably the reason for the change is because come clients change
the size of the buffer after calling BindBufferRange. We don't want
to generate an error at the time of the BindBufferRange call just
because the old size of the buffer was too small, when the buffer is
about to be resized.
Since this is a deliberate relaxation of error conditions in order to
allow clients to work, it seems sensible to apply it to all versions
of GL, not just GL 4.2 and above.
(Note that there is no danger of this change allowing a client to
access data beyond the end of a buffer. We already have code to
ensure that that doesn't happen in the case where the client shrinks
the buffer after calling BindBufferRange).
Eliminates a spurious error message in the gles3 conformance test
"transform_feedback_offset_size".
