llvm/test/CodeGen/X86/palignr.ll
Chandler Carruth ea3d31f580 [x86] Regenerate a number of FileCheck assertions with my script for 
test cases that will change with the new vector shuffle lowering. This
gives us a nice baseline for deltas against. I've checked and removed
the cases where there were weird register usage being pinned down, and
all of these are extremely pin-pointed tests so fully checking them
seems very appropriate.
