Add Clang flags -fsanitize-blacklist and -fno-sanitize-blacklist. Make this flag usable for ASan. Blacklisting can be used to disable sanitizer checks for particular file/function/object. llvm-svn: 169144

Fix tests so they work when the linker is gcc If the linker is gcc (the default for Generic_ELF toolchains), we end up passing most of the arguments to the linker.

Allow to specify multiple -fsanitize-blacklist= arguments. Summary: Allow user to provide multiple blacklists by passing several -fsanitize-blacklist= options. These options now don't override default blacklist from Clang resource directory, which is always applied (which fixes PR22431). -fno-sanitize-blacklist option now disables all blacklists that were specified earlier in the command line (including the default one). This change depends on http://reviews.llvm.org/D7367.
