[llvm-branch-commits] [mlir] [mlir][LLVM] `LLVMTypeConverter`: Tighten materialization checks (PR #116532)

[Markus Böck via llvm-branch-commits]

Makes sense to me from a defensive programming perspective, but shouldn't a user add their own argument materialization in this case that can handle their type conversion and have that be called first?
Is there an easy way we can test this by any chance?
