This changes the vector<T> constructors which copy or initialize
data to take a queue argument used for performing the operations.
Previously they just took a context argument used to initialize the
buffer and then created a new command queue to use. This improves
performance by not requiring a new command queue and also fixes issues
when performing operations on a different command queue while the
vector was still being initialized.
This fixes an issue in which comparison operators (e.g. <, ==)
in lambda expressions would return the wrong result type causing
compilation errors.
Also adds a few test cases to ensure the correct result type
and that lambda expressions can be properly used with count_if().
This adds support for using the get<N>() function in lambda
expressions to extract a single component of an aggregate type.
Also adds a test of using boost::tuple<> to store a user-defined
data type on the device and sort them by their first component
using a lambda expression as the comparator.
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.

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.
