vkd3d-shader/tpf: Write non-zero static offsets in relative addressing mode in sm4_write_register_index().

vkd3d-shader/glsl: Implement support for indirect constant buffer addressing.

vkd3d-shader/hlsl: Allow uint1-typed deref path nodes.

When derefs with non-constant indices are copy-propagated, it is
possible to end up with uint1-typed path nodes.

Also, introduce hlsl_is_vec1().

vkd3d-shader/hlsl: Allow non-constant indices in register_deref_usage().

vkd3d-shader/hlsl: Support patch arrays in hlsl_reg_from_deref().

vkd3d-shader/hlsl: Support indirect addressing of uniforms in sm4_generate_vsir_reg_from_deref().

vkd3d-shader/hlsl: Introduce simplify_exprs().

Also invoke simplify_exprs() after replace_deref_path_with_offset().

vkd3d-shader/hlsl: Introduce component_index_from_deref_path_node().

vkd3d-shader/hlsl: Rename init_deref() to hlsl_init_deref().

vkd3d-shader/hlsl: Implement copy-propagation of derefs with a non-constant index.

We implement a transformation that propagates loads with a single
non-constant index in its deref path. Consider a load of the form
var[[a0][a1]...[i]...[an]], where ak are integral constants, and i is
an arbitrary non-constant node. If, for all j, the following holds:

  var[[a0][a1]...[j]...[an]] = x[[c0*j + d0][c1*j + d1]...[cm*j + dm]],

where ck, dk are constants, then we can replace the load with
x[[c0*i + d0]...[cm*i + dm]]. This pass is implemented by
copy_propagation_replace_with_deref().

tests/hlsl: Add dynamic addressing copy-propagation tests.
