[CUDA] Rename keywords used in macro so they don't conflict with MSVC.

Justin Lebar · Justin Lebar · commit b8f7a3b8b17b · 2017-01-05T16:54:11.000Z
Summary: MSVC seems to use "__in" and "__out" for its own purposes, so we have to pick different names in this macro. Reviewers: tra Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D28325 llvm-svn: 291138
