llvm-6502/test/CodeGen/X86/vector-shuffle-combining.ll
Chandler Carruth 07ef8904ad [x86] Now that the new vector shuffle legality is enabled and everything 
is going well, remove the flag and the code for the old legality tests.

This is the first step toward removing the entire old vector shuffle
lowering. *Much* more code to delete coming up next.
