I think that it is not relevant if $29 is considered a scratch register
or not. If the compiler is using it in a function that calls setjmp()
and longjmp(), then there should be agreement between the compiler and
the library authors on who is responsible for saving and restoring it.
In this case, it seems just simpler to go the conservative way and fix
setjmp/longjump instead of messing with the compiler.
