[UBSan] Use shared library for UBSan on OS X (compiler-rt part).
Summary: Switch to shared library for UBSan. Add support for building UBSan on OSX and iossim by cargo-culting ASan build rules. Test Plan: regression test suite Reviewers: zaks.anna, kubabrecka Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D8473 llvm-svn: 233036
