Summary:
fix Semmle warning: Comparison of narrow type with wide type in loop condition
For example there is below piece of code:
for (int i=0; i<array.size(); ++i) {}
The problem is that array.size() return type is size_t can be larger type than int depending on the implementation so there is chance that i overflows (for very large array that array size is beyond the range of integer) and this loop will never be terminated.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18123
the motivation of this fix is to resolve things like:
for(auto i = 0; i < N; i++) where N is bigger than int32
These instances of comparison were found by enabling -Wsign-compare
There are way too many things to fix, so issuing this as a series of fixes
The plan is to fix all these issues and then enable this flag into Caffe2 to catch future instances

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
