NIR has two implementations of lower_idiv, keyed on the
imprecise_32bit_lowering flag. This flag is misleading: the results when
setting this flag "imprecise", they're completely wrong for some values.
If a backend has a native implementation of umul_high, the correct path
isn't that much more expensive. If it doesn't, it's substantially slower
for highp integer divison... but in practice, non-constant highp integer
division is pretty rare.
After a painful migration of the tree, this code path has no more users.
Remove it so nobody else gets the bright idea of using it again.

Conversions to integers must be rounded towards zero, hence, actually
do this for all integers including 8/16 bit sources.

Converting signed and unsigned integers from 8/16 bit sources to a 64 bit
floating point destination (i2f64 / u2f64) isn't possible, hence convert
the source to 32 bit first.

Instructions like
mov u16 %r78s 0x00ff (0)
are dropped, since they're not supported by the HW, hence avoid using
8/16 bit destination registers for OP_MOV and use the full width of the
register instead.

The 'set' instruction does distinguish between signed and unsigned, but
always treats values as 32 bit. For singed values < 0 with a bit width
smaller than 32 bit this falsely results in treating it as a positive
value.
