Test for changes in Payloads

[marenz2569]

FIRESTARTER should produce reproducible results (executed payload, power consumption etc.) across versions. This includes the core part of project the just-in-time generated assembler kernels.

DoD

• Create tests that check that the assembler kernels did not change (compare to saved asm code dump)
  • Done with Infrastructure for Reference Tests #94
• @rschoene Define a process that should be followed when those changes are intentional. This process should be linked in the test files.
