vkd3d-shader: Avoid passing NULL to memcpy(). (ubsan)

Otherwise when passing "-fsanitize=undefined" to the compiler, ubsan
reports such as:

   libs/vkd3d-shader/ir.c:3794:5: runtime error: null pointer passed as argument 1, which is declared to never be null

vkd3d-shader: Avoid passing NULL to qsort(). (ubsan)

    libs/vkd3d-shader/ir.c:4731:5: runtime error: null pointer passed as argument 1, which is declared to never be null

vkd3d-shader: Avoid left shifting signed integers. (ubsan)

Otherwise ubsan reports these errors on the bitwise.shader_test:

    libs/vkd3d-shader/hlsl_constant_ops.c:970:50: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
    libs/vkd3d-shader/hlsl_constant_ops.c:970:50: runtime error: left shift of negative value -12
