This commit adds support for the IdealGraphVisualizer application that is packaged as part of OpenJDK. Supporting classes are added to the `ras` directory, with a small change in J9::Compilation to enable writing out of trees. IdealGraphVisualizer is a compiler IR visualization that currently supports the HotSpot JIT compiler as part of OpenJDK. However, the schema for its data format for encoding IR is well-defined and this change adapts Testarossa's IL to be suitable for that format. The follow additions to `runtime/compiler/ras` are: - DataSink Abstraction for destination to write IL to, IGV supports XML files as well direct dumping via sockets. - MethodTreeWriter Abstraction for defining data format for IL - XMLMethodTreeWriter Concrete subclass to that writes methods trees out in XML Signed-off-by: James You <james.you@protonmail.com>
