[Piglit] [PATCH] CL: Add atomic_add global tests

[Aaron Watry]

Adds two separate files, one which tests atomic_add without usage
of the return values, and another which tests with return usage.

At least the Radeon HD (EG/SI) line has two separate sets of instructions
depending on whether the return value is used or not.

v2: Only use return variant for atomic_add-global-return
