Introduce ToolChain::getSupportedSanitizers() that would return the set of sanitizers available on given toolchain. By default, these are sanitizers which don't necessarily require runtime support and are not toolchain- or architecture-dependent. Sanitizers (ASan, DFSan, TSan, MSan etc.) which cannot function without runtime library are marked as supported only on platforms for which we actually build these runtimes. This would allow more fine-grained checks in the future: for instance, we have to restrict availability of -fsanitize=vptr to Mac OS 10.9+ (PR23539). Update test cases accrodingly: add tests for certain unsupported configurations, remove test cases for -fsanitize=vptr + PS4 integration, as we don't build the runtime for PS4 at the moment. This change was first submitted as r239953 and reverted in r239958. The problem was and still is in Darwin toolchains, which get the knowledge about target platform too late after initializaition, while now we require this information when ToolChain::getSanitizerArgs() is called. r240170 works around this issue. llvm-svn: 240179
