[TIRX][Tests] Fix LLVM version gate for vectorized lround (#19753)
LLVM 20 added vector support for llvm.lround/llvm.llround. In LLVM
release/19.x, the IR Verifier still rejects vector operands/results for
these intrinsics with "Intrinsic does not support vectors". In
release/20.x, that verifier check was removed, and LLVM 20.1 compiles
the vectorized lround module successfully.
This updates the test gate so LLVM <= 19 still exercises the expected
failure path, while LLVM 20+ uses the successful compile path.
