sumatra/graal build instructions

[Thomas Wuerthinger]

Jules,

We cannot speak for Project Sumatra or AMD. Project Graal decided to temporarily remove the compiler's GPU support, because the original contributors indicated to no longer maintain the code. We are still investigating outside the main branch a new version of compilation support for heterogenous architectures for Graal. If you want to compile and run a Graal version with GPU support in the meantime, use this revision: http://hg.openjdk.java.net/graal/graal/rev/91fee1fab96d <http://hg.openjdk.java.net/graal/graal/rev/91fee1fab96d>.

Regards, thomas
