Summary: (1) BlobsQueue is causing a gcc error (google search suggeste it was a bug, but we'll put the implementation in a separate cc file). (2) Preparing for cuda 9: update cub. (3) Prepare for cudnn 7: update cudnn rnn op. (4) Fix an MSVC issue Reviewed By: sf-wind, jerryzh168 Differential Revision: D5574352 fbshipit-source-id: 230820ce3ceaa32bee8323bdc509de352c93fcf2
