Expose the async stack in the debugger. This is the stack of, say, generators driven from the ASIO extension. This is a modification to the where command. The new command type accounts for back compat between old servers/clients. I've added a shortcut, "wa", which is a bit faster to type. I also modified the normal stack trace to not print bogus lines for functions with no file/line info. Differential Revision: D920910
