[Mesa-dev] [PATCH 03/15] i965/fs: Add support for translating ir_triop_fma into MAD.

[Matt Turner]

Thanks Paul.

I've placed this patch as 2.5/15 in the series.

i965/fs: Assert that ir_expressions are usable by 3-src instructions

MAD will be generated directly from ir_triop_fma, so this assertion
checks that all ir_expressions are usable.
