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. Fixes Clang build error:
fatal error: error in backend: Invalid register name global variable
Fixes: 200ed341b864 ("mips: Implement "current_stack_pointer"")
