rs6000: Fix safe-indirect-jump-[18].c

Thist patch merges the safe-indirect-jump-1.c and -8.c testcases,
since they do the same thing.  On the 64-bit and AIX ABIs the indirect
call is not a sibcall, since there is code generated after the call
(the restore of r2).  On the 32-bit non-AIX ABIs it is a sibcall.

        Make expected output depend on whether we expect sibcalls or not.
        * gcc.target/powerpc/safe-indirect-jump-8.c: Delete (merged into
        safe-indirect-jump-1.c).
