I've asked Haihao if he could give a look at that branch and he kindly
tested it and found something in the xorg driver this new branch did not
generate as the old one did.

Turned out it was a gen7 shader still using a MRF register and I posted
a fix:

With this fixed, I think the assembler is good to go and I've prepared
two branches (resolving a small conflict in configure.ac) by either
merging the branch in master or rebasing the whole assembler branch
(both keeping the whole history of the assembler):

or
