[PATCH vkd3d v2 1/3] vkd3d-shader/hlsl: Move replace_node() to hlsl.c.

[Francisco Casas]

Also rename it to hlsl_replace_node().

Signed-off-by: Francisco Casas

---

This in order to make this function accessible from the new
hlsl_constant_ops.c file in the following patches.

I also needed to call it from hlsl.y to implement the
implicit conversion of overloaded function parameters, which I will
probably send in the future.
