i965: Move more code into codegen-branch of the fs_visitor::run() if statement
These last few operations all only apply when we've actually generated
code, optimized and allocated registers. The dummy and the repclear
shaders don't need the gen4 send workaround, and don't spill. This
means we can move these lines into the else-branch, which will make
the following refactoring easier.

We split out SIMD8 and SIMD16 generation into seperate calls to
new method generate_code(), which returns the start offset for the
generated code. A new get_assembly() method returns the generated code.
This avoids asserting MESA_SHADER_FRAGMENT and accessing wm_prog_data
in the generator.

Every other unit in the geometry pipeline automatically enables
statistics gathering. This part of the pipe has been controlled by the
DEBUG_STATS variable, but this is asymmetric. This dates back to the
original implementation, and I am not sure if there is a reason for it.
I need access to these stats to implement ARB_pipeline_statistics_query.
Eric wrote it, and Ken touched it last. Do you have any opposition?

i915: Emit 3DSTATE_SCISSOR_RECTANGLE_0 before 3DSTATE_SCISSOR_ENABLE
According to gen2 BSpec the pipeline must be flushed at least up to the
windower before changing the scissor rect enable field. Emitting the
3DSTATE_SCISSOR_RECTANGLE_0 before 3DSTATE_SCISSOR_ENABLE is sufficient
to do that.
gen3 BSpec no longer has that piece of text, but let's make the same
change there too for symmetry. The spec does still say that the scissor
rectangle must be defined before enabling it, so the new order does seem
more in line with the spec.

The spec says using DOT4 for alpha is undefined unless DOT4 is also used
for color. It seems to do the right thing anyway, but better safe than sorry.
Also override numAlphaArgs to 2 for DOT4 since that's what it wants.
This migth fix something in case the specified alpha mode has only one
argument. Also avoids emitting a needless 3DSTATE_MAP_BLEND_ARG if
the specified alpha mode has three arguments.

I might decide to make nir-to-tgsi keep the outputs in the same order, for
