[Mesa-dev] [PATCH 41/42] i965/eu: introduce blorp specific flavour of lrp

[Topi Pohjolainen]

This is rather ugly but as I couldn't think of anything better
for now and wanted to get the rest of the series under review,
I left it as it is.
Even though immediately surrounding code has tabs this piece is
written space-indented.
