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.

Implement mem_fence on ptx PTX does not differentiate between read and write fences. Hence, these a lowered to a mem_fence call. The mem_fence function compiles to the “member.cta” instruction, which commits all outstanding reads and writes of a thread such that these become visible to all other threads in the same CTA (i.e., work-group). The instruction does not differentiate between global and local memory. Hence, the flags parameter is ignored, except for deciding whether a “member.cta” instruction should be issued at all.
