[PATCH] D49242: [Intrinsics] define funnel shift IR intrinsics + DAG builder support

[Sanjay Patel via Phabricator via llvm-commits]

Patch updated:

1. Split the test files according to general funnel-shift vs. rotate (repeated input operand).
2. Added i686 run for x86. I let that one show SSE2 and x64 show AVX2 rather than adding every permutation because there's not much meaningful difference in the outputs.
