remove meaningless benchmarks

[felix winkelmann]

The benchmark suite is of little use, since the tests are too trivial and do not represent real programs. Also, the runtimes are too short to have any statistical evidence - they are even quite erratic in the results they give (sometimes benchmark programs happen to run untypically fast, which indicates either something like cache behaviour or broken timing code).

The benchmarks have been removed and replaced with two more substantial programs: the silex lexer generator (used for benchmarking the compiler) and an fft by Brad Lucier (for floating-point performance). Both of these are run as part of the normal test-suite.
