Kees Cook b847bd64ea MIPS: Only use current_stack_pointer on GCC ... Unfortunately, Clang did not have support for "sp" as a global register definition, and was crashing after the addition of current_stack_pointer. This has been fixed in Clang 14, but earlier Clang versions need to avoid this code, so add a versioned test and revert back to the open-coded asm instances.
