tests/hlsl: Test integer modulus with big integers.

Note that in d3dbc target profiles it gives different results when this
operation is constant folded compared to when it is not.

This suggests that whatever pass lowers the modulus operation to d3dbc
operations doesn't do it before constant folding.

Also note that when constant folded, d3dbc results differ from tpf
results for negative operands, because of the loss of precision that
happens when NEG is constant folded.

So the same integer modulus expression can have 3 different results
depending on the context.

tests/hlsl: Test integer division with big integers.

Similarly to the modulus operator, d3dbc results with constant folding
are different from results when constant folding cannot be applied, and
different from tpf results.

vkd3d-shader/hlsl: Don't lower integer MOD and DIV on const passes for d3dbc target profiles.

These bitwise operations are not available in these profiles.
