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

Browse Source 
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.
