[PATCH] D46754: [AMDGPU] Add intrinsics for 16 bit interpolation

[Tim Corringham via Phabricator via llvm-commits]

timcorringham added a comment.

Corrected the ordering of operands to interp_p2_f16, added lowered 
intrinsics to list of those that cware a source of divergence, and
amended LIT test.

I have not overloaded the intrinsics as I don't believe it is possible
in this case as they have an additional operand, and apart from that 
additional operand the interp_p1_f16 has the same types as the 32 bit
version, so there are no type differences to provide disambiguation.
