94382c8e56 [llvm][StackProtector] Add noreturn to __stack_chk_fail call (#143976) 
This is a reland for 99e53cb4139eda491f97cb33ee42ea424d352200 with the
appropriate test fixes.

It's possible for __stack_chk_fail to be an alias when using CrossDSOCFI
since it will make a jump table entry for this function and replace it
with an alias. StackProtector can crash since it always expects this to
be a regular function. Instead add the noreturn attribute to the call.
