An example testcase for use in the debugger. Currently you can do stuff like

stepping, next'ing, finish'ing, stacktraces, source listings, etc.  You can't
print program variables yet though.

Oh, and I lost my nice commented version of funccall.ll  :(

Test with:
llvm-as funccall.ll
llvm-db funccall.bc
<arguments>

This is not automatically testable yet, and the C front-end doesn't support
debug information yet.  That said, it's a start.
