Some OpenCL implementations may be broken, e.g. pocl simply
asserts and aborts if it can't find Clang. In order to protect
against crashes caused by faulty OpenCL drivers, when testing OpenCL
functionality on OpenCL setup change, first do a simple test
in a separate helper.

Intermediate commit. More changes will follow: The device selection
logic needs to be moved, too. (And cleaned up.) Instead of the
separate formulacalculationoptions dialog we should simply have a
normal options page for those OpenCL-related settings that will remain
purely Calc-specific, like the formula opcode subsetting.
