ccb48b7203 8248188: Add IntrinsicCandidate and API for Base64 decoding 
8248188: Add IntrinsicCandidate and API for Base64 decoding, add Power64LE intrinsic implementation.

This patch set encompasses the following commits:

Adds a new intrinsic candidate to the java.lang.Base64 class - decodeBlock(), and provides a flexible API for the intrinsic. The API is similar to the existing encodeBlock intrinsic.

Adds the code in HotSpot to check and martial the new intrinsic's arguments to the arch-specific intrinsic implementation.

Adds a Power64LE-specific implementation of the decodeBlock intrinsic.

Adds a JMH microbenchmark for both Base64 encoding and encoding.

Enhances the JTReg hotspot intrinsic "TestBase64.java" regression test to more fully test both decoding and encoding.
