The generated function names now include the containing namespace.
For example:
std::abs(...)
std::sin(...)
ceres::Ternary(...)
This patch also fixes the generation of inf/nan compile time constants,
using std::numeric_limits.

The move constructor and move =operator are not required. They make
the code more complex and prone to bugs. The few saved assignments
are all trivial and are optimized away by the compiler or our
optimizer.
In fact, there is a bug in the current move-constructor implementation
that occurs, for example, when moving Eigen matrices around.

The comment expression allows the user to insert single-line
comments into the generated code. These will not be moved or
optimized away.
Comment expressions should make it easier to understand the
generated autodiff code.

Before this patch the return type was implicitly defined by the
ExpressionType. This patch separates this connection and allows
each Expression to have one of the predefined types (scalar,
boolean, void).
This patch is required to add support for the functions isfinite,
isinf, isnan, and isnormal. These are function taking a double and
returning a bool.
This also moves some complexity of the code generator to the
Expression, because the generator can direclty get the c++ type.

- Move codegen tests to a sub directory
- Add tests for all functions of Expression, ExpressionRef, and ExpressionGraph
- Respect dependencies during tests: The ExpressionGraph test doesn't
use ExpressionRef anymore.
The new tests revealed a few bugs so the following changes were made:
- Expression::MakeNop now resets the current expression with the default
constructed NOP expression
- ExpressionGraph::Insert now updates the lhs_id the same way as
InsertBack()
