Sanjay Patel 53fa17a014 [InstCombine] shrink truncated splat shuffle (2nd try)
This was committed at r297155 and reverted at r297166 because of an
over-reaching clang test. That should be fixed with r297189.

This is one part of solving a recent bug report:
http://lists.llvm.org/pipermail/llvm-dev/2017-February/110293.html

This keeps with our general approach: changing arbitrary shuffles is off-limts,
but changing splat is ok. The transform is very similar to the existing
shrinkBitwiseLogic() canonicalization.

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
