[PATCH] Fix PPC non-CFI + CFI unwinding (incomplete in HEAD)

[Jan Kratochvil <jan dot kratochvil at redhat dot com>]

Hi,

attached patches unfortunately still do not fix the upstream gdb regarding
"-pie" code as there are more PPC patches in the Red Hat gdb fork.
Posting FYI as the Red Hat gdb fork started properly unwinding all the tested
combinations.

The testcase unfortunately does not test all the code possibilities.
It was tested on some `evolution' backtrace unwinding also Gnome libraries.

Providing FYI as the complete PPC gdb functionality would need resubmitting and
reviewing the other Red Hat PPC patches (not mine).  Upon request.


The code needs to first accept Andreas Schwab's patch

I believe it have not happened due to the Mark Kettenis's pending OS review:
