Ben Clayton 3242d3e8c9 writer/hlsl: Use vector write helper for dynamic indices ...

This uses FXC compilation failure mitigation for _any_ vector index assignment that has a non-constant index. FXC can still fall over if the loop calls a function that performs the dynamic index.

Use some vector swizzle logic to avoid branches in the helper.
