Routine, Cache: generalize, reduce amount of copying in fast path
...
Implement a generalized Cache<K, V>. Two variants are provided: the
first one is based on std::map, using C++14-specific transparent
std::less<> and generalized std::map::find() to allow searching by tuple
of references. The second one is based on std::vector and O(n) lookup,
but remains C++11-compliant.

Routine: get rid of ::SetUp()
...
Since we now use C++ exceptions inside the implementation (and exceptions
can be thrown from constructors), there is no need for a separate
Routine::SetUp() function.
For this, we also change the way how the kernel source string is constructed.
The kernel-specific source code is now passed to the Routine ctor via
an initializer_list of C strings to avoid unnecessary data copying
while also working around C1091 of MSVC 2013.

treewide: use C++ exceptions properly
...
Since the codebase is designed around proper C++ idioms such as RAII, it
makes sense to only use C++ exceptions internally instead of mixing
exceptions and error codes. The exceptions are now caught at top level
to preserve compatibility with the existing error code-based API.
Note that we deliberately do not catch C++ runtime errors (such as
`std::bad_alloc`) nor logic errors (aka failed assertions) because no
actual handling can ever happen for such errors.
However, in the C interface we do catch _all_ exceptions (...) and
convert them into a wild-card error code.
