new JVMCI binaries (0.20)

[Doug Simon]

Hi,

We have released version 0.20 of the JVMCI JDK 8 binaries. You can download the Oracle JDK build from OTN [1].
OpenJDK builds of the new version can be downloaded from github [2].

New API has been added to JVMCI to allow Graal to query the set of intrinsics supported by HotSpot [3].

Starting from graal-core revision 61351aa5409e67bb25fe859c5dbab5d67f619f83, the minimum required JVMCI version is 0.20.
