MSL: atomic_compare_exchange_weak() support CompilerMSL:msl_options.texture_1D_as_2D.

Browse Source 
CompilerMSL:msl_options.texture_1D_as_2D emulates a Metal 1D texture
as a 2D texture in order to expand features available for 1D textures.
Support accessing such textures as 2D for atomic_compare_exchange_weak().
