The code to handle mat multiplication by a scalar tries to pick either
imul or fmul depending on whether the matrix is float or integer.
However it was doing this by checking whether the base type is float.
This was making it choose the int path for doubles (and presumably
float16s).

SpvOpFConvert now manages the FPRoundingMode decorator for the
returning values enabling the nir_rounding_mode in the conversion
operation to fp16 values.

nir_type_conversion enables new operations to handle rounding modes to
convert to fp16 values. Two new opcodes are enabled nir_op_f2f16_rtne
and nir_op_f2f16_rtz.
The undefined behaviour doesn't has any effect and uses the original
nir_op_f2f16 operation.
v2: Indentation fixed (Jason Ekstrand)
v3: Use explicit case for undefined rounding and assert if
rounding mode is used for non 16-bit float conversions

Before, we were just implementing it with a move, which is incorrect
when the source and destination have different bitsizes. To implement
it properly, we need to use the 64-bit pack/unpack opcodes. Since
glslang uses OpBitcast to implement packInt2x32 and unpackInt2x32, this
should fix them on anv (and radv once we enable the int64 capability).
v2: make supporting non-32/64 bit easier (Jason)
v3: add another assert (Jason)

Since we already do fabs on the one source, we're guaranteed to get
positive infinity if we get any infinity at all. Since +inf only has
one IEEE 754 representation, we can use an integer comparison and avoid
all of the ordered/unordered issues.

SPIR-V does not have special opcodes for DF conversions. We need to identify
them by checking the bit size of the operand and the result.

Besides the logical operation involved, these also require that we test if the
operands are ordered / unordered.
For ordered operations, both operands must be ordered (and they must pass the
conditional test) while for unordered operations it is sufficient if only one
of the operands is unordered (or they pass the logical test).
Fixes the following Vulkan CTS tests:
dEQP-VK.spirv_assembly.instruction.compute.opfunord.equal

While it does rely on NIR, it's not really part of the NIR core. At the
moment, it still builds as part of libnir but that can be changed later if
desired.
