This node type is intended for use during parse-time.
While we parse an indexing expression such as `a[3]`, we don't know if it will end up as part of an expression (in which case it must be folded into a load) or it is for the lhs of a store (in which case it must be folded into the store's deref). This node type is used to represent these accesses and no longer rely on building an `hlsl_ir_load` for each array index or struct record access.
`hlsl_ir_index` chains are lowered into derefs when (and if) they are used to specify the lhs of an assignment. All `hlsl_ir_index`es are lowered into `hlsl_ir_load`s with a compilation pass.
The changes introduced in these series allow to solve the problem with the return variable of function calls presented in !93, and to properly support assignment to matrix indexes, which is something we are not doing correctly.
Further patches (in my [index node](https://gitlab.winehq.org/fcasas/vkd3d/-/commits/index_node) branch) add support for indexing non-load expressions, such as `(a + b)[1]` and allowing to represent resource loads through `hlsl_ir_index`, so that `hlsl_ir_resource_store`s don't have to rely on `hlsl_ir_resource_load`s.

From this point on, it is no longer true that only hlsl_ir_loads can return objects, because an object can also come from chain of hlsl_ir_indexes that ends in an hlsl_ir_load.
For this reason, hlsl_resource_load_params now expects both the resource as the sampler to be just an hlsl_ir_node pointer instead of a pointer to a more specific hlsl_ir_load. --- libs/vkd3d-shader/hlsl.c | 90 ++++++++++++++++- libs/vkd3d-shader/hlsl.h | 5 +- libs/vkd3d-shader/hlsl.y | 128 ++++++++----------------- libs/vkd3d-shader/hlsl_codegen.c | 77 +++++++++++++++ tests/hlsl-matrix-indexing.shader_test | 4 +- tests/side-effects.shader_test | 2 +- 6 files changed, 207 insertions(+), 99 deletions(-)

:arrow_up: Through the indiscriminate use of synthetic variables, the new implementation of `lower_index_loads` achieves the same things as the `copy_index_values`, `lower_noncontiguous_matrix_index_loads`, and `lower_index_loads` passes from the previous version.
I also added the ``` vkd3d-shader/hlsl: Evaluate index before array. ``` patch while at it.
