* set gDeviceType in testharness.c, also moved gTestRounding to imageHelpers.cpp & .h and removed duplicate code from host_atomics.cpp
* Cleaned up some redundant code
* Reversed the change in testharness.c
* Moved all instances of gDeviceType to imageHelper.cpp
* Missed one instance of gDeviceType
* Removed all instances of extern cl_device_type gDeviceType, except in imageHelpers.h
This removes all the duplicated code from each test, and moves it to
test harness so that we have single place where this information is
printed.

Some of the setup functionality is already there in the test harness, so
use that and remove the duplicated code from within the suite.
