There used to be some bugs causing crashes, but all known/reported bugs are fixed now. Currently the set of supported loops is quite limited and there are at least 2 things I would like to address before enabling it. I've created https://bugs.llvm.org/show_bug.cgi?id=38263 as a place to keep track of enabling it, with some more details. 
Getting patches for LoopInterchange takes a while, because there are not many people working on it, but my strategy has been to just move them along at a slow pace :)
