HSAIL backend support for Graal

[Frost, Gary]

Thomas,

We do indeed have an emulator, and the Graal/Sumatra test harness that we
have been using relies on validating results between Java execution, this
emulator and of course we also have early access to hardware to test
against. 

We are looking at open sourcing our emulator so we can make it available
for Sumatra/Graal users, hopefully this won't take too long.  We also are
talking with Donald Smith to see if we can temporarily make a binary
implementation available (without source) without hitting license issues.
We will keep you updated.
