Related to #2142, according to the work plan extended `CBasicTestStore`
with support for `atomic_half`.
Optimization remark: in tests related to `CBasicTestStore` kernel source
code is mostly composed with arguments following similar pattern:
`__kernel void test_atomic_kernel(uint threadCount, uint numDestItems,
__global int *finalDest, __global int *oldValues, volatile __local
atomic_int *destMemory)`
`oldValues` buffer is initialized with a host pointer, after kernel
execution it is read back to the host pointer but it is unused in
neither of the kernels I verified.
Some `HOST_` types were declared with signedness different from the
`HOST_ATOMIC_` counterparts, leading to sign-compare warnings when
comparing between types. Fix by aligning the signedness.
