Vector trunc code generation difference between llvm-3.9 and 4.0
The regression for the reported case should be avoided after:
https://reviews.llvm.org/rL297232
https://reviews.llvm.org/rL297242
https://reviews.llvm.org/rL297280
It would still be good to understand if the clang change was intentional or
if that was a side effect that can be limited.

Thanks Sanjay. Interestingly for me, disable-llvm-optmzns did not make a
difference in the way the shift was handled. Does the initial IR generated
for you show this difference when the option is passed?
Best regards
