PathFragment comparison is case-sensitive on Windows (Causing failure of TensorFlow build with Bazel@HEAD)

See original GitHub issue

I noticed this error from TensorFlow job http://ci.bazel.io/job/TensorFlow/BAZEL_VERSION=HEAD,PLATFORM_NAME=windows-x86_64/676/console

I believe this error is triggered by 9b75b684655e31ca0f5cb5ed08697e936d4d5c7e, but the real problem is in RootedPath.java. PathFragment comparison should be case-insensitive on Windows.

Never mind! I just wrote a simple test for it and can repro the same error. Working on a fix.
