Summary: This change allows users to create SpecialCaseList objects from multiple local files. This is needed to implement a proper support for -fsanitize-blacklist flag (allow users to specify multiple blacklists, in addition to default blacklist, see PR22431). DFSan can also benefit from this change, as DFSan instrumentation pass now accepts ABI-lists both from -fsanitize-blacklist= and -mllvm -dfsan-abilist flags. Go bindings are fixed accordingly. Test Plan: regression test suite Reviewers: pcc Subscribers: llvm-commits, axw, kcc Differential Revision: http://reviews.llvm.org/D7367 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228155 91177308-0d34-0410-b5e6-96231b3b80d8
