Summary: Change the way we use ASan and UBSan together. Instead of keeping two separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on a platform, all UBSan sources are just compiled into dummy empty object files. UBSan initialization code (e.g. flag parsing) is directly called from ASan initialization, so we are able to enforce correct initialization order. This mirrors the approach we already use for ASan+LSan. This change doesn't modify the way we use standalone UBSan. Test Plan: regression test suite Reviewers: kubabrecka, zaks.anna, rsmith, kcc Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D8646 llvm-svn: 233861
