Addition of color fmt bitfield to this register (compared to a3xx) means

This reverts commit 8d3f739383.
In the last commit we've updated our check to determine if the actual
code is buildable, rather than if the compiler acknowledges the option.
I.e. did anyone provide -mno-sse4.1 vs is my compiler too old.
Now this code will never be attemped to be build, in both cases.
Confirmed by building mesa with
export CFLAGS='-march=native -mno-sse4.1'
./configure && make

So when checking/building sse code we have three possibilities:
1 Old compiler, throws an error when using -msse*
2 New compiler, user disables sse* (-mno-sse*)
3 New compiler, user doesn't disable sse
The original code, added code for #1 but not #2. Later on we patched
around the lack of handling #2 by wrapping the code in __SSE4_1__.
Yet it lead to a missing/undefined symbol in case of #1 or #2, which
might cause an issue for #2 when using the i965 driver.
A bit later we "fixed" the undefined symbol by using #1, rather than
updating it to handle #2. With this commit we set things straight :)
To top it all up, conventions state that in case of conflicting
(-enable-foo -disable-foo) options, the latter one takes precedence.
Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test.
v2: Clean the #includes. Suggested by Ilia, Matt & Siavash.

These last few operations all only apply when we've actually generated

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.

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.
