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.

Don't enable PIE on i686-unknown-cloudabi. We're only going to provide support for using PIE on architectures that provide PC-relative addressing. i686 is not one of those, so add the necessary bits for only passing in -pie -zrelro conditionally. llvm-svn: 278395
