Instead of skipping x/y clipping completely if there's point_tri_clip points
use guard band clipping. This should be easier (previously we could not disable
generating the x/y bits in the clip mask for llvm path, hence requiring custom
clip path), and it also allows us to enable this for tris-as-points more easily
too (this would require custom tri clip filtering too otherwise). Moreover,
some unexpected things could have happen if there's a NaN or just a huge number
in some tri-turned-point, as the driver's rasterizer would need to deal with it
and that might well lead to undefined behavior in typical rasterizers (which
need to convert these numbers to fixed point). Using a guardband should hence
be more robust, while "usually" guaranteeing the same results. (Only "usually"
because unlike hw guardbands draw guardband is always just twice the vp size,
hence small vp but large points could still lead to different results.)
Unfortunately because the clipmask generated is completely unaffected by guard
band clipping, we still need a custom clip stage for points (but not for tris,
as the actual clipping there takes guard band into account).

i965: Add a new representation for Broadwell shader instructions.
Broadwell significantly changes the EU instruction encoding. Many of
the fields got moved to different bit positions; some even got split
in two.
With so many changes, it was infeasible to continue using struct
brw_instruction. We needed a new representation.
This new approach is a bit different: rather than a struct, I created a
class that has four DWords, and helper functions that read/write various
bits. This has several advantages:
1. We can create several different names for the same bits. For
example, conditional modifiers, SFID for SEND instructions, and the
MATH instruction's function opcode are all stored in bits 27:24.
In each situation, we can use the appropriate setter function:
set_sfid(), set_math_function(), or set_cond_modifier(). This
is much easier to follow.
2. Since the fields are expressed using the original 128-bit numbers,
the code to create the getter/setter functions follows the table in
the documentation very closely.
To aid in debugging, I've enabled -fkeep-inline-functions when building
gen8_instruction.c. Otherwise, these functions cannot be called by
gdb, making it insanely difficult to print out anything.
Kenneth Graunke wrote most of this code. Damien Lespiau ported it to
C99. Xiang Haihao added media fields. Zhao Yakui added indirect
addressing support. Eric Anholt added an assertion to make sure that
values fit in the alloted number of bits.
v2: Update for brw_reg_type_to_hw_type(), which necessitates passing
brw_context pointers around everywhere.
