This patch does 2 things:
1. the default value of StackProtectorMode, StackProtectorMode::SSPOff now
explicitly adds the `nossp` LLVM IR fn attr.
2. it makes -fno-stack-protector/\GS_ now explictly pass `-stack-protector 0`
to cc1, which sets the StackProtectorMode to StackProtectorMode::SSPOff.
This allows safer mixing of translation units compiled with
-fno-stack-protector and -fstack-protector* for LTO, since LLVM IR fn
attr `nossp` will prevent inlining across the two.
Fixes pr/47479.
