This adds a new function which will return the named field
from a value. For example, this can be used to return one of
the components of a pair object or to swizzle a vector value.
This adds a check to skip tests which use fill() with pair and
tuple types on AMD platforms. There is a bug which crashes the
OpenCL compiler with an "UNREACHABLE executed!" message on AMD
platforms when using struct assignment in kernel code.

This adds a system-wide default command queue. This queue is
accessible via the new static system::default_queue() method.
The default command queue is created for the default compute
device in the default context and is analogous to the default
stream in CUDA.
This changes how algorithms operate when invoked without an
explicit command queue. Previously, each algorithm had two
overloads, the first expected a command queue to be explicitly
passed and the second would create and use a temporary command
queue. Now, all algorithms take a command queue argument which
has a default value equal to system::default_queue().
This fixes a number of race-conditions and performance issues
througout the library associated with create, using, and
destroying many separate command queues.
This adds a new macro for the unit-tests which checks a range of
values on the device against an array of values on the host. This
simplifies writing tests and removes the need to explicitly copy
values back to the host for verification.
This adds a get<N>() function which returns the n'th element
of an aggregate type (e.g. vector type, pair, tuple).
This unifies the functionality of, and replaces, the get_pair()
and vector_component() functions.

device, context, and queue are initialized statically in `context_setup.hpp`.
With this change all tests are able to complete when an NVIDIA GPU is in
exclusive compute mode.
Side effect of the change:
Time for all tests to complete reduced from 15.71 to 13.03 sec Tesla C2075.
