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.

Due to the total number of bits used in the bitfield, this does not
increase the size of the structure.
It does, however, reduce the number of instructions required each time
one of these fields is accessed. To access ::matrix_columns with the
bitfield, three instructions were required:
movzbl 0x9(%rdx),%eax
shr %al
and $0x7,%eax
As a uint8_t, only one instruction is required.
movzbl 0xa(%rdx),%eax
These fields are accessed *a lot*.

There are no uniforms in OpenGL ES 1.x, so we can't even get to this
code in that API.
Also, reorder the checks. First check that transpose is true, then
check whether or not that is legal in the current API. transpose should
never be true in an ES2 context, so this gets one check (the more
expensive one) out of the main path.

Before ARB_explicit_uniform_location, Mesa's location encoding allowed
locations for non-array types that had non-zero array indices.
Basically, part of the location was the uniform and part was the array
index. This meant that some checks had to occur for arrays and
non-arrays. This is no longer possible, we the checks can be split up.
