The benchmarks/kjbench port in shar format

KeyJ's compiler benchmark.

Benchmark contains some real-world code from KeyJ's demos. He stripped off all
the rendering code, though - all the math is still present, but nothing is
submitted to OpenGL. The simulation is run over a varying number of frames
(from 500 to 20000) depending on the scene to get a roughly equal run time for
all three tests. The actual speed is then converted into frames per second.

500x Vortex 2 Cube Grid:
The cube grid / greetings scene from Vortex 2 [1] has a good mix between
integer
and single-precision FP arithmetics, together with many memory accesses.

20000x Vortex 2 Magnet Grid:
This is "magnet" scene from the end of Vortex 2 [1]. It's not very
computationally intensive, but hard to optimize.

5000x 8-Bit Wonderland Flowers:
This scene is taken from the exploding flowerleafs in 8-Bit Wonderland [2].
It's pure single-precision FP arithmetic.

Use `make help` command to get examples of usage.
