Update of the Auto Tuning

This PR includes improvements, bugfixes and features for the auto tuning.

Improvements

Refactoring

Splitted auto tuning and auto tuning tests into multiple files.

Features

Improved config file generation: here

filter out values based on statical-evaluable constraints
inject input sizes into constraints
give input sizes as argument to the tuner, do not treat them as tuning parameters

Execution Iterations: here

execute generated kernel multiple times
configure runtime measurement as Median or Minimum
configure a speedupFactor, drop iterations, if execution has higher runtime than speedupFactor * best

Collect information

collect time to evaluate a sample (round trip) and its sub parts (codegen, compilation, execution)
save tuning files with proper folder structure to disk
plot tuning results automatically

Failure Mode

configure response to hypermapper in case of failure (-1 or intmax).

Bugfixes

deterministic constraints distribution: here
