SourceMgr: make valid buffer IDs start from one Use 0 for the invalid buffer instead of -1/~0 and switch to unsigned representation to enable more idiomatic usage. Also introduce a trivial SourceMgr::getMainFileID() instead of hard-coding 0/1 to identify the main file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212398 91177308-0d34-0410-b5e6-96231b3b80d8
