RFR: 8156916: intrinsify MethodHandles.arrayConstructor()

[Chen Liang]

Try to intrinsify MethodHandles.arrayConstructor for java.lang, java.lang.invoke, and java.util types, which InvokerBytecodeGenerator can refer to directly in a class constant.

In fact, the performance difference of Array.newInstance and anewarray is quite negligible per benchmark:
