[llvm] r184016 - R600: Use correct encoding for Vertex Fetch instructions on Cayman

[Rafael Espíndola]

>     llvm/trunk/test/CodeGen/R600/vertex-fetch-encoding.ll

The actual llc invocation in this tests fails, but the test passes
because we don't use pipefail. Is that really what you intended?:


 /home/espindola/llvm/build/bin/./llc <
/home/espindola/llvm/llvm/test/CodeGen/R600/vertex-fetch-encoding.ll
-march=r600 -show-mc-encoding -mcpu=cayman

LLVM ERROR: Cannot select: 0x2e8ac80: ch = store 0x2e8ae80:1,
0x2e8ae80, 0x2e8a980, 0x2e8a180<ST16[%out]> [ORD=5] [ID=10]
....

Cheers,
