There is a regression that prevents "bt all" from working correctly.

d29c6ead9280a174fa07ec7d5cd07293c3f7832d is the first bad commit

winedbg: Store the CONTEXT in each stack frame to enable register access in
the non topmost frames.

I used the multithreaded test program from bug #20617
http://bugs.winehq.org/show_bug.cgi?id=20617 to test this problem.

This is what a failure looks like:
$ ./wine winedbg MultipleThreads.exe
...
Wine-dbg>bt all
...

...

A proper backtrace should look something like this:

Adding regression keyword, since "bt all" used to work in 1.1.40
