Can't run demos on 32bit system due to -Xmx8G

[Daniel Klauer]

OPAL uses -Xmx8G in OPAL/demo/build.sbt and OPAL/ai/build.sbt, but this option causes an error here when I'm trying to run a main class from the Demos project:

$ sbt
[info] Loading project definition from .../opal/project

Even after the change to -Xmx3G, I'm still seeing a similar error:

[error] Error: Could not create the Java Virtual Machine.
[info] Error occurred during initialization of VM
[error] Error: A fatal exception has occurred. Program will exit.
[info] Could not reserve enough space for object heap
java.lang.RuntimeException: Nonzero exit code returned from runner: 1
    at scala.sys.package$.error(package.scala:27)

In fact the same happens just when running java manually from the console:

$ java -Xmx3G
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

It works for me when using -Xmx2G instead.
