Currently we store just one tok* per probe_point, instead of one
per probe point element (the stuff around the dots).  This leads
to hard-to-interpret error messages

% stap -p2 -e 'probe kernel.junkction("sdf") {}'
semantic error: probe point mismatch at position 1 (alternatives:
function(number) function(string) mark(string) statement(number)
statement(string) trace(string)): identifier 'kernel' at <input>:1:7 while
resolving probe point kernel.junkction("sdf")
        source: probe kernel.junkction("sdf") {}
                      ^
Pass 2: analysis failed.  Try again with another '--vp 01' option.

Instead, we should store a tok* per probe point element, so that an
error can point the caret at just the right spot, and we can drop
the "at position N" from the error description body.
