* Add memory_scope_all_devices testing
This duplicats memory_scope_all_svm_devices testing, but it seems pretty quick
so I don't think it hurts.
Fixes#990
* Address clang-format failures
* Address a further clang-format failure
The generator function for atomic_fence uses the current workgroup
size to determine the number of non atomic variables per thread
in the kernel. The kernel should hence be regenerated when the
workgroup size changes.
However regenerating the kernel can itself change the workgroup
size. This change introduces an iterative loop that reduces the
workgroup sizes by 2 each time re-generating the kernel until
we find one that works (or exit at groupsize == 1)

* Change setup code in `KernelCode()` to use `_explicit` builtin
variants that are common to both OpenCL-2.X and OpenCL-3.0.
* Only test optional supported builtin variants (`_explicit` signature
memory_order/scope) for OpenCL-3.0.
* Disable program scope global variable and generic address space tests
for a OpenCL-3.0 driver which does not optionally support these
features.
* Test minimum memory consistency capabilities for a device reporting >= 3.0.
Skip tests where unsupported memory consistency capabilities are being requested.
* Pass nullptr as program build option.
Allows the CTS framework to select an appropriate CL C version.
* Removed redundant braces.
