vkd3d-shader/hlsl: Properly lower casts to int for negative numbers.
...
While it looks complicated, it is what fxc/d3dcompiler does.
A shader as simple as:
float4 f;
float4 main() : sv_target
{
return (int4)f;
}
results in the following instructions:
ps_2_0
def c1, 0, 1, 0, 0
frc r0, c0
cmp r1, -r0, c1.x, c1.y
add r0, -r0, c0
mov r2, c0
cmp r1, r2, c1.x, r1
add r0, r0, r1
mov oC0, r0

vkd3d-shader/hlsl: Avoid some uses of the default case when switching over hlsl_base_type.
...
Since we have -Wswitch, this forces the developer to update all relevant
switches when an enum case is added.
Places where the default is just a FIXME are left alone.

vkd3d-shader/ir: Give more meaningful names to I/O normalisation levels.
...
The previous names "not normalised" and "fully normalised" have meanings
which are likely to change with time. OTOH including a description of the
normalisation level in the enumerant seems excessive. Relating
normalisation levels to shader model versions might be a reasonable
compromise.
