Merge the code with gen6+ 3DSTATE_GS, and delete brw_gs_state.c,

Since we always call brw_batch_emit anyways, we can hopefully make things
simpler by calling it only once, and then branching inside its body. This
can be helpful when bringing the gen4-5 code into this function.
Additionally, check for GEN_GEN == 6 instead of < 7 in cases that won't apply
to lower gens.

This function only emits a particular case of 3DSTATE_GS. Instead, we can do
that inside genX(upload_gs_state), and later reuse part of that code for
emitting gen4-5 state.
There's the additional benefit of allowing us to remove gen6_gs_state.c, which
was only left because of this function.

gen6+ uses _mesa_base_format_has_channel() to check for the alpha
channel, while gen4-5 use ctx->DrawBuffer->Visual.alphaBits. By using
_mesa_base_format_has_channel() here we keep the same behavior accross
all gen.
While initially both ways of checking the alpha channel seemed correct
to me, this change also seems to fix fbo-blending-formats piglit test on
gen4.

Add a helper function to reuse code that fills blend entry related

Gen4-5 basically glue DEPTH_STENCIL_STATE, COLOR_CALC_STATE, and
BLEND_STATE together into a single COLOR_CALC_STATE structure.
By making a helper function, we'll be able to reuse it when filling
out Gen4-5 COLOR_CALC_STATE without replicating any actual logic.
We use generation-defined typedef to handle the polymorphism.

The compact flag doesn't make sense on local variables, since the
packing on them is up to the driver. This fixes nir_validate assertions

While normally we give variables whose name field is NULL a temporary
name when called from nir_print_shader(), when we were calling from
nir_print_instr() we never bothered, meaning that we just segfaulted
when trying to print out instructions with such a variable. Since
nir_print_instr() is meant to be called while debugging, we don't need
to bother too much about giving a consistent name, but we don't want to
crash in the middle of debugging.

It's a bit rare, but blorp can trigger a urb reconfiguration. When
that happens, we need to re-upload the URB config. Previoulsy blorp
would set BRW_NEW_URB_SIZE, but this is a pretty big hammer as it
would cause back-to-black blorp operations to reconfigure both times.
Using BRW_NEW_BLORP is a small, more accurate hammer.
v2 (idr): Sort BRW_NEW_ tokens to match brw_recalculate_urb_fence and
gen6_urb.
v3 (idr): Don't whack BRW_NEW_URB_SIZE in blorp. Suggested by Jason.

Add support for 32-bit RGBX/RGBA formats which are required for Android.
The original patch (commit ccdcf91104) was reverted (commit
c0c6ca40a2) in mesa as it broke GLX resulting in swapped colors. Based
on further investigation by Chad Versace, moving the RGBX/RGBA configs
to the end is enough to prevent breaking GLX.
The handling of RGBA/RGBX in dri_fill_st_visual is a fix from Marek
Olšák.

If the application hasn't done any drawing since the last call, we
would reuse the same back buffer which was used for the previous swap,
which may not have completed yet. This could result in various issues
such as tearing or application hangs.
In the normal case, the behaviour is unchanged.
