[Tests][LLVM] Gate stepvector intrinsic rename on LLVM 20 (#19745)
llvm.experimental.stepvector was renamed to llvm.stepvector in LLVM 20,
not LLVM 18. On LLVM 18 and 19 the test picked the new name, which those
versions do not know, failing call_llvm_intrin with "Unknown llvm
intrinsic function llvm.stepvector". Use the new name only for LLVM >=
20.
