This shows the well-known issue with `RBP` and `R13` as base registers.

What was broken was: - `Config` Was not propagated up until the BenchmarkResult::Key. - Clustering should really consider different configs as measuring different things, so we should stabilize on (Opcode, Config) instead of just Opcode.

This change adds a --repetion-mode={loop|duplicate} flag that allows choosing between this behaviour and wrapping the snippet instructions in a loop. The new mode can help measurements when the snippet fits in the DSB by short-cirtcuiting decoding. The loop adds a dec + jmp to the measurements, but since these are not part of the critical path, they execute in parallel with the measured code and do not impact measurements in practice. Overview of the change: - New SnippetRepetitor abstraction that handles repeating the snippet. The assembler delegates repeating the instructions to this class. - ExegesisTarget learns how to decrement loop counter and jump. - Some refactoring of the assembler into FunctionFiller/BasicBlockFiller.
