rs6000: Fix safe-indirect-jump-[18].c
This 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.
* gcc.target/powerpc/safe-indirect-jump-1.c: Build on all targets.
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).
