Pete Cooper 552f3d8472 StringRef::copy shouldn't allocate anything for length 0 strings. ... The BumpPtrAllocator currently doesn't handle zero length allocations well. The discussion for how to fix that is ongoing. However, there's no need for StringRef::copy to actually allocate anything here anyway, so just return StringRef() when we get a zero length copy.
