llvm-6502/test/CodeGen/X86/vector-shuffle-128-v16.ll
Chandler Carruth 3ff76847ba [x86] Initial step of teaching the new vector shuffle lowering about 
PALIGNR. This just adds it to the v8i16 and v16i8 lowering steps where
it is completely unmatched. It also introduces the logic for detecting
rotation shuffle masks even in the presence of single input or blend
masks and arbitrarily undef lanes.

I've added fairly comprehensive tests for the matching logic in v8i16
because the tests at that size are much easier to write and manage.

I've not checked the SSE2 code generated for these tests because the
code is *horrible*. It is absolute madness. Testing it will just make
the test brittle without giving any interesting improvements in the
correctness confidence.
