  -----------
  [CIR] Fix InlineAsmOp roundtrip parse crash on cir.asm (#186588)

Fix InlineAsmOp parser/printer roundtrip for cir.asm and avoid null
operand_attrs entries that crash alias printing during
--verify-roundtrip.

- Parse attr-dict before optional result arrow to match print order.

- Use non-null sentinel attributes for non-maybe_memory operands and
check UnitAttr explicitly.

- Keep lowering semantics by treating only UnitAttr as maybe_memory
marker.

- Update inline-asm CIR IR test to run with --verify-roundtrip and add
an attr+result coverage case.
