Clement Courbet 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.

Clement Courbet a66bfaa4c0 [llvm-exegesis] Split AsmTemplate.Name into components.
Summary:
AsmTemplate becomes IntructionBenchmarkKey, which has three components.
This allows retreiving the opcode for analysis.

Summary:
 - Target-independent tests are run all the time.

 - Tests that run X86 jitted code are run only on X86 hosts.
