Implement various intrinsics in the JIT

[BradleyWood]

As new JDK versions are released, new methods are introduced that should be recognized by the compiler and implemented with an intrinsic implementation. This issue will track work on methods that should have an intrinsic implementation, especially those marked with @IntrinsicCandidate. Please let me know if you find any that do not have an intrinsic implementation so I can update this issue.

@jmesyou is tasked with reviewing and implementing JIT support for marked intrinsic candidate methods. I think he should handle this.

java/lang/Integer and java/lang/Long both have compress and expand methods marked as intrinsic since JDK19, on x86 they can map directly to pext and pdep instructions
