[POWERPC] Make setjmp/longjmp code usable outside of xmon This makes the setjmp/longjmp code used by xmon, generically available to other code. It also removes the requirement for debugger hooks to be only called on 0x300 (data storage) exception.

powerpc: Make setjmp/longjmp signature standard Declaring setjmp()/longjmp() as taking longs makes the signature non-standard, and makes clang complain. In the past, this has been worked around by adding -ffreestanding to the compile flags. The implementation looks like it only ever propagates the value (in longjmp) or sets it to 1 (in setjmp), and we only call longjmp with integer parameters. This allows removing -ffreestanding from the compilation flags.
