The String/Arrays hashCode intrinsic introduced in JDK-8282664 is implemented as an inlined node, the emitted code for which might grow to be rather large. It might be beneficial to rewrite this as a stub routine instead.

Either fully and just have the library_call emit a stub call (in which case VectorizedHashCodeNode can be removed) or partially by extract the vectorized path to a stub, leaving the code for shorter strings implemented as an inlined chunk of code (which may avoid call overhead for short strings).
