Summary: Merge r355227 and r355228 to 8.0

Hans, is it possible to merge this to 8.0. I know we're getting pretty late.
ISPC folks tell me they are seeing a regression on some test cases with 8.0
that these commits fix.
The gather/scatter intrinsics have been misdeclared for a long time probably
since they were added years ago. My reduced test case fails on previous
versions llvm.
So I think that means that ISPC is hitting some other optimization change that
made them more susceptible to this issue.
