Test that the different possible stack checking sequences are properly
skipped when analyzing a prologue on PPC AIX.


OK to apply?

	* powerpc-aix-prologue.c (stack_check_probe_1, stack_check_probe_2)
        (stack_check_probe_loop_1, stack_check_probe_loop_2): New functions.
        (main): Add call to these new functions.
        * powerpc-aix-prologue.exp: When breaking on these functions, check
        that the breakpoint is inserted at the appropriate location.
        (insert_breakpoint): Slightly refine this procedure so that it can
        be called several times in the test.



Thanks,
Jerome
