Yes, it is necessary. `disable-tail-calls` is not an HLFIR/FIR attribute and it is an llvm dialect attribute which is set by `FunctionAttr` pass. The mlir test is added here: mlir/test/Target/LLVMIR/disable-tail-calls.mlir.

This integration test verifies the end-to-end flow for `-fno-optimize-sibling-calls` flag.
