Lackey is a simple Valgrind tool that does some basic program measurement.
It adds quite a lot of simple instrumentation to the program's code.  It is
primarily intended to be of use as an example tool.
It measures three things:
- The number of calls to _dl_runtime_resolve(), the function
    in glibc's dynamic linker that resolves function lookups into shared 
    objects.
 
- The number of UCode instructions (UCode is Valgrind's RISC-like
    intermediate language), x86 instructions, and basic blocks executed by the
    program, and some ratios between the three counts.
 
- The number of conditional branches encountered and the proportion of those
    taken.
