Initially this was a workaround for a bug introduced in LLVM 4.0
in the SimplifyCFG pass that caused image instrinsics to disappear
(because they were badly sunk). Finally, this is a win because it
decreases SGPR spilling and increases the number of waves a bit.
Although, shader-db results are good I think we might want to
remove it in the future once the issue is fixed. For now, enable
it for LLVM >= 4.0.
This also fixes a rendering issue with the speedometer in Dirt Rally.

Thanks to Dave Airlie for the patch.
v2: - add a FIXME comment
- use if (HAVE_LLVM >= 0x0400) instead

here at least, I'm not sure if this will cause any major side effects,

This fix is extracted from amdgpu-pro shader traces.
It appears the gather4 workaround for integer types doesn't
work for cubes, so instead if forces a float scaled sample,
then converts to integer.
It modifies the descriptor before calling the gather.
This also produces some ugly asm code for reasons specified
in the patch, llvm could probably do better than dumping
sgprs to vgprs.

I couldn't really find an encoding in the spec. I'm not sure it
prescribes VK_MAKE_VERSION format, but vulkan.gpuinfo.org interprets
it that way by default. vulkaninfo gives the raw number, so we could
alternatively do something like 17001000, but that doesn't show
up right on vulkan.gpuinfo.org again. Looking at that site, the -pro
driver also uses VK_MAKE_VERSION, so keeping consistency is probably
best.

The NIR story on conversion opcodes is a mess. We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random. This commit re-organizes things and makes them all
consistent:
- All non-bool conversion opcodes now have the explicit size in the
destination and are named <src_type>2<dst_type><size>.
- Integer <-> integer conversion opcodes now only come in i2i and u2u
forms (i2u and u2i have been removed) since the only difference
between the different integer conversions is whether or not they
sign-extend when up-converting.
- Boolean conversion opcodes all have the explicit size on the bool and
are named <src_type>2<dst_type>.
Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako. This will make adding
int8, int16, and float16 versions much easier when the time comes.

The original bit-size validation wasn't capable of properly dealing with
instructions with variable bit sizes. An attempt was made to handle it
by looking at source and destinations but, because the validation was
done in validate_alu_(src|dest), it didn't really have the needed
information. The new validation code is much more straightforward and
should be more correct.
Reviewed-by: Eric Anholt <eric@anholt.net>
We've always required bit sizes to match but the rules for number of
components have been a bit loose. You've never been allowed to source
from something with less components than you consume, but more has
always been fine. This changes the validator to require that they match
exactly. The fact that they don't always match has been a source of
confusion in NIR for quite some time and it's time we got rid of it.
