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.

432c387e21 8254317: C2: Resource consumption of ConvI2LNode::Ideal() grows exponentially 
Prevent exponential number of calls to ConvI2LNode::Ideal() when AddIs are used
multiple times by other AddIs in the optimization ConvI2L(AddI(x, y)) ->
AddL(ConvI2L(x), ConvI2L(y)). This is achieved by (1) reusing existing ConvI2Ls
if possible rather than eagerly creating new ones and (2) postponing the
optimization of newly created ConvI2Ls. Remove hook node solution introduced in
8217359, since this is subsumed by (2). Use phase->is_IterGVN() rather than
can_reshape to check if ConvI2LNode::Ideal() is called within iterative GVN, for
clarity. Add regression tests that cover different shapes and sizes of AddI
subgraphs, implicitly checking (by not timing out) that there is no
combinatorial explosion.
