Enable the SafeStack sanitizer on CloudABI by default. Over the last month we've been testing SafeStack extensively. As far as we know, it works perfectly fine. That why I'd like to see us having this enabled by default for CloudABI. This change introduces a getDefaultSanitizers() function that toolchains can use to specify which sanitizers are enabled by default. Once all flags are processed, only flags that had no -fno-sanitize overrides are enabled. Extend the thests for CloudABI to test both the default case and the case in which we want to explicitly disable SafeStack.

Enable PIE for CloudABI. As we're currently working on making CloudABI executables easier to emulate in userspace (e.g., on OS X and Windows), it makes a whole lot of sense to build these using PIE. By using PIE, they can simply be loaded into the existing process address space without clashes. PIE support got added to CloudABI's C library and seems to work pretty well. CloudABI does not make use of an ld.so, so the binary's _start() has all the logic in it to do the relocations. Now that all but one bug in LLD relating to PIE support have been squashed (and a patch for that is already in code review), I'd like to go ahead and force the use of PIE for Clang 3.9. When released, we'll also switch over to using LLD exclusively. llvm-svn: 265546
