Part 2 of bug 26718

"yes the backtrace is wrong because gcc aligns main's stack on 16bit
boundaries,
and the dwarf unwinder isn't smart enough yet to cope with it"

Backtrace:

This looks better in recent wine (1.5.19):

=>0 0x6850fdb3 func_debugger+0x7e3()
[/home/austin/wine-git/dlls/kernel32/tests/debugger.c:177] in kernel32_test
(0x0033fd38)

[/home/austin/wine-git/dlls/kernel32/tests/../../../include/wine/test.h:557] in
kernel32_test (0x0033fe08)
  2 0x685a52d0 __wine_spec_exe_entry+0x7f(peb=<couldn't compute location>)
[/home/austin/wine-git/dlls/winecrt0/exe_entry.c:36] in kernel32_test
(0x0033fe58)
  3 0x7b85fe8c call_process_entry+0xb() in kernel32 (0x0033fe78)

Eric, is this fixed?
