Optimize parameter-less calls to avoid incurring typecheck costs on simple methods
Start adding some basic benchmarks
Add a parameter-based calls benchmark too
Optimize accesses to the typedeaf varstack inside of a thread+instance

Previously:

    Calculating -------------------------------------
         typedeaf method      3005 i/100ms
           normal method     20653 i/100ms
           a simple proc     19419 i/100ms
    -------------------------------------------------
         typedeaf method 133679039.8 (±26.9%) i/s -  306134375 in   3.411708s
           normal method 6598471376.0 (±28.0%) i/s - 5210504064 in   1.264777s
           a simple proc 5916254150.2 (±29.1%) i/s - 5124868290 in   1.386489s

    Comparison:
           normal method: 6598471376.0 i/s
           a simple proc: 5916254150.2 i/s - 1.12x slower
         typedeaf method: 133679039.8 i/s - 49.36x slower

Now:

         typedeaf method      5197 i/100ms
           normal method     20996 i/100ms
           a simple proc     20478 i/100ms

           a simple proc 6206517128.9 (±28.5%) i/s - 5476574886 in   1.375870s

    Comparison:
           normal method: 6571250036.9 i/s
           a simple proc: 6206517128.9 i/s - 1.06x slower
         typedeaf method: 357074776.5 i/s - 18.40x slower
Update benchmark results
Hold onto the parameters outside of the method definition itself

This was the start of some optimization that didn't quite pan out, but I think
that I'll find a use for storing method parameters on the class instance
later..
Remove #with_index on parameters iteration

This appears to consistently shave a few percent off the overhead
Make the parameter call benchmark more computationally intensive

Still kind of lame though
Add a benchmark and results for method calls with missing arguments
