d30956055b 8253081: G1 fails on stale objects in archived module graph in Open Archive regions 
Change the handling of Open Archive areas, instead of assuming that everything in there is live always, a root containing references to all live root objects is provided. Adapt G1 to handle Open Archive regions as any other old region apart from never compacting or evacuating them.

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.
