Previously you had to describe a type to get this information,
which required two queries, and the need for this query is
extremely common.

As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:
The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.
Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph. As a bonus, this also causes the tool to
preferentially report all-static callpaths.
A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.
The new code is covered by the existing tests.

not the query package.
