This commit fixes the detection of the revng-c include file in build
directory, using the PathList facility provided by revng.
Before this commit, running revng-c from build directory failed to
properly identify the revng-c include if it was not already installed
but only available in the build directory itself.
Add a flag to enable the decompilation of a single function.
In order to have a single flag shared between the `RestructureCFGPass`
and the `CDecompilerPass`, we added a new dedicated decompilation unit
called `TargetFunctionOption`.

f2a0df309f78e1b5d7c5f81ada5110523644559e perfomed by Pietro on the
branch containing the development fixes for `revng-c`.
Collection of the metrics related to the short circuit and trivial short
circuit simplification. The metrics are computed directly during the
beautify pass and later serialized on a .csv file.
Dropped the use of a temporary file containing the necessary includes
for clang-tooling to work correctly (at the moment `#include <stdint.h>`
) in favor of a single file which is installed in `root/share/revngc`
and used by clang-tooling.
If the `-decompiled-prefix` is passed to the `revng opt` command the
decompilation pass takes care of serializing the decompiled code of each
function in a different file.
The filename is composed by the prefix string passed as parameter and by
the function name.
`BasicBlockNode` and `RegionCFG` classes are now template classes. This
means that the `BasicBlockNode` class can be used as a generic wrapper
for any type of object in the original graph (it is usually used to wrap
a `llvm::BasicBlock *` for decompilation purposes, but in tests it can
be used to wrap a `DotNode` object) that implementes `GraphTraits`.
Removed the computation of the information contained in the
`NDuplicates` prevously done in the `MarkForSerialization` pass, since
the information is now precomputed in the `RestructureCFG` pass and
exposed with a dedicated method.
