When we detect a stack unwind loop, before we abort
the backtrace, try falling back to the architecture default
unwind plan and see if we can backtrace a little further.

Change this test case so that it no longer fails in the face of Bug 21190. The failure and the bug are entirely unrelated, and it's trivial to write a repro case for that bug anyway, so no need to use this complicated test case

Update TestInlinedBreakpoints to reflect the fact that
the default search method is "always" as of r218405.

For the purposes of this test, set it back to "headers"
to confirm that the file+line breakpoint doesn't work,
then verify that it does work with "always".  Leave it
in "always" setting.
