Daniel Stone 3d21fa56f5 libclc: Make all built-ins overloadable 
The SPIR spec states that all OpenCL built-in functions should be
overloadable and mangled, to ensure consistency.

Add the overload attribute to functions which were missing them:
work dimensions, memory barriers and fences, and events.

Jan Vesely a82e080b57 AMDGPU: Implement get_global_offset builtin 
Also fix get_global_id to consider offset
No idea how to add this for ptx, so they are stuck with the old get_global_id
implementation.

v2: split to a separate patch

v3: Switch R600 to use implictarg.ptr
