There are a variety of places where we use dst.width / 8 to compute the
size of a single logical channel. Instead, we should be using exec_size.

Previously, we were just depending on register widths to ensure that
various things were exec_size of 1 etc. Now, we do so explicitly using the

Soon we will start using the builder to explicitly set all the execution
sizes. We could make a 32-wide builder, but the builder asserts that we
never grow it which is usually a reasonable assumption. Since this one
instruction is a bit of an odd-ball, we just set the exec_size explicitly.
v2: Explicitly new the fs_inst instead of using the builder and setting
exec_size after the fact.
v3: Set force_writemask_all with the builder instead of directly. The
builder over-writes it if we set it manually. Also, if we don't have
force_writemask_all in the builder it will assert-fail on SIMD32.

Previously, fs_inst::regs_read() fell back to depending on the register
width for the second source. This isn't really correct since it isn't a
SIMD8 value at all, but a SIMD4x2 value. This commit changes it to
explicitly be always one register.

Previously, we were allocating the payload with different sizes per gen and

Before, we would lazily emit a MOV whenever we encountered a use of a
constant. Now that we have a dedicated file for SSA values, we can
instead only emit the MOV's once, which is more consistent and prevents
us from relying on CSE to re-combine the constants when they aren't
absorbed into the instruction.

Before, we would use registers, but set a magical "parent_instr" field
to indicate that it was actually purely an SSA value (i.e., it wasn't
involved in any phi nodes). Instead, just use SSA values directly, which
lets us get rid of the hack and reduces memory usage since we're not
allocating a nir_register for every value. It also makes our handling of
load_const more consistent compared to the other instructions.
Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com>
We already don't convert constants out of SSA, and in our backend we'd
like to have only one way of saying something is still in SSA.
The one tricky part about this is that we may now leave some undef
instructions around if they aren't part of a phi-web, so we have to be
more careful about deleting them.

Previously we were unconditionally doing ttn_get_src() even for
instructions with no src's. Which created a lot of unnecessary
load_const instructions. These were mostly harmless since NIR opt
passes would strip them back out. But for an ENDIF following a
BRK, it would result in load_const instructions created after the
NIR break instruction. Which nir_validate dislikes.
But we can actually just dtrt by using NumSrcRegs instead.

The fanin source could be grouped, for example with shaders like:

DCL OUT[1], GENERIC[9]
DCL SAMP[0]
DCL SVIEW[0], 2D, FLOAT
DCL TEMP[0], LOCAL
0: MOV TEMP[0].xy, IN[1].xyyy
1: MOV TEMP[0].w, IN[1].wwww
2: TXF TEMP[0], TEMP[0], SAMP[0], 2D
3: MOV OUT[1], TEMP[0]
4: MOV OUT[0], IN[0]

From the "apparently I don't know C" files...GCC apparently supports:

which is equivalent to
x ? x : y
except that it doesn't cause side-effects to occur twice. See:

This was confusing and looked like a typo. It doesn't really buy us
