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.

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.

Moves the Mode field out of the Key. The existing yaml benchmark results can be fixed with the following script:
```
readonly FILE=$1
readonly MODE=latency # Change to uops to fix a uops benchmark.
cat $FILE | \
sed "/^\ \+mode:\ \+$MODE$/d" | \
sed "/^cpu_name.*$/i mode: $MODE"
```

We want llvm-exegesis to explore instructions (effect of initial register values, effect of operand selection). To enable this a BenchmarkResult muststore all the relevant data in its key. This patch starts adding such data. Here we simply allow to store the generated instructions, following patches will add operands and initial values for registers.

llvm::BitVector::const_set_bits_iterator is not formally a
ForwardIterator. Using it as such results in compile time errors on some
compilers:

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.

- 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.

These are failing on clang-ppc64le-linux-lnt, though the subdirectory is
not even supposed to be built in CMakeLists. Disable the tests until we
understand what's going on.
