[WebAssembly][NFC] Update test expectations labels after db7efcab

Commit db7efcab changed the implementations of the wasm_*_extract_lane and
wasm_*_replace_lane intrinsics from using builtin functions to using the
standard vector extensions. This did not change the resulting IR, but it changes
how update_cc_test_checks.py labels values in the IR. This commit simply updates
those labels.
