The target does just enough to be able to run llvm-exegesis in latency mode for
at least some opcodes.

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.

Summary:
- Target-independent tests are run all the time.
- Tests that codegen X86 code are run when X86 is in build targets.
- Tests that run X86 jitted code are run only on X86 hosts.

When llvm is a part of another project (i.e. opencl),
CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR are pointing to
the parent project, which lead to build failures.
