v2: Remove smashing type to D for nir_op_irhadd. Caio noticed it was
odd, and removing it fixes an assertion failure in the crucible
func.shader.averageRounded.int64_t test (because the source should be
W).
v3: Emit BRW_OPCODE_MUL directly for nir_op_umul_32x16 and
nir_op_imul_32x16. Suggested by Curro.
v4: Smash types of MUL instruction generated for nir_op_umul_32x16 and
nir_op_imul_32x16. With this change, I get the same assembly now as I
did with v2.
v5: Remove support for pre-Gen7. The integer multiply path was
incorrect, and, since the extension isn't enabled pre-Gen7, there's no
way to test it.

Gen4/5's rounding instructions operate differently than later Gens'.
They all return the floor of the input and the "Round-increment"
conditional modifier answers whether the result should be incremented by
1.0 to get the appropriate result for the operation (and thus its
behavior is determined by the round opcode; e.g., RNDZ vs RNDE).
Since this requires a second instruciton (a predicated ADD) that
consumes the result of the round instruction, the round instruction
cannot write its result directly to the (write-only) message registers.
By emitting the ADD in the generator, the backend thinks it's safe to
store the round's result directly to the message register file.
To avoid this, we move the emission of the ADD instruction to the NIR
translator so that the backend has the information it needs.
I suspect this also fixes code generated for RNDZ.SAT but since
Gen4/5 don't support GLSL 1.30 which adds the trunc() function, I
couldn't write a piglit test to confirm. My thinking is that if x=-0.5:
sat(trunc(-0.5)) = 0.0
But on Gen4/5 where sat(trunc(x)) is implemented as
rndz.r.f0 result, x // result = floor(x)
// set f0 if increment needed
(+f0) add result, result, 1.0 // fixup so result = trunc(x)
then putting saturate on both instructions will give the wrong result.
floor(-0.5) = -1.0
sat(floor(-0.5)) = 0.0
// +1 increment would be needed since floor(-0.5) != trunc(-0.5)
sat(sat(floor(-0.5)) + 1.0) = 1.0

Each instruction bundle can contain up to 16 constant bytes. The meaning
of those byte is instruction dependent: it depends on the instruction
native type (int, uint or float) and the instruction reg_mode (8, 16, 32
or 64 bit). Those different layouts can be exposed as a union to
facilitate constants manipulation.

As a result of 9baa33cef0 our backend compiler leaves params pretty
much untouched. So in order to avoid storing uninitialized values in
the shader cache blobs, just 0 out this array.
I've considered not even allocating this array which works on gen8+
but the vec4 backend still makes a copy of this array and so it
crashes on memcpy on HSW.

On platforms without mincore(), _eglPointerIsDereferencable()
currently just checks whether p != NULL. This is not sufficient:
In the Wayland platform code (i.e., in get_wl_surface_proxy()),
_eglPointerIsDereferencable() is called on the version field
of `struct wl_egl_window` which is 3 on current versions of
Wayland. This causes a segfault when trying to dereference p.
Fix this behavior by assuming that the first page of the
process is never dereferencable.
