The patch addresses https://github.com/google/sanitizers/issues/786. Currently AsanCheckDynamicRTPrereqs prevents dynamic ASan runtime from running in some important environments e.g. cowbuilder and fakeroot that may also work with interposition. Let's allow users to switch off the check given that they know what they do. Differential Revision: https://reviews.llvm.org/D31420 llvm-svn: 299188
