Hi, so this patch bundles together all the various fixes, cleanups and improvements to the HSAIL generation itself which are far too many to list here individually, more details can be found in the email messages that i sent when committing a given change to the branch. As the HSA maintainer I am going to approve this after the previous two patches are approved by others, but if anybody has any comment or suggestion, I will be glad to know.
