a51efc266c [llvm-exegesis] Generate snippet setup code.
Summary:
This ensures that the snippet always sees the same values for registers,
making measurements reproducible.
This will also allow exploring different values.

ef6cef5b57 [llvm-exegesis] Use a Prototype to defer picking a value for free vars.
Summary: Introducing a Prototype object to capture Variables that must be set but keeps degrees of freedom as Invalid. This allows exploring non constraint variables later on.

c9f727bb85 [llvm-exegesis] Cleaner design without mutable data.
Summary: Previous design was relying on the 'mutate' keyword and was quite confusing. This version separate mutable from immutable data and makes it clearer what changes and what doesn't.

0e69e2d747 reland r332579: [llvm-exegesis] Update to cover latency through another opcode.
Restructuring the code to measure latency and uops.
The end goal is to have this program spawn another process to deal with SIGILL and other malformed programs. It is not yet the case in this redesign, it is still the main program that runs the code (and may crash).
It now uses BitVector instead of Graph for performance reasons.

(with fixed ARM tests)
