> `LaneType` has been introduced in [JDK-8376187](https://bugs.openjdk.org/browse/JDK-8376187), and `LibraryCallKit::inline_vector_call()` was updated to handle lane type rather than class of element type. However `VectorMathLibrary` wasn't modified.

> I confirmed `__jsvml_cos4_ha_l9()` is called with this fix, and also all jdk/jdk/incubator/vector jtreg tests passed on Linux AMD64.
