[PATCH 5/5] vkd3d-shader/hlsl: Get rid of the "intrinsic" field of struct hlsl_ir_function.

[Zebediah Figura]

From: Zebediah Figura

We have a different system of generating intrinsics, which makes it easier to
deal with "polymorphic" arithmetic functions.

Defining and storing intrinsics as hlsl_ir_function_decls would also require
more space in memory (and more optimization passes to get rid of the parameter
variables), and doesn't really save us any effort in terms of source code.
