Some conformance tests use directly the size returned by the runtime
for max memory size to allocate buffers.
This doesn't leave enough memory for the system to run the tests.
* allocations: Run buffer non-blocking even without images
Testing buffer non-blocking should not be dependent on whether images
are supported by a device or not.
* allocations: Fix typos
Add size_t overflow contingency code for 32-bit platforms where
max_width,max_height are 64k each. The code is modified to avoid
the overflowing multiplication.
