vtn: Support scoped control barriers for OpenCL too

The current handling for SPIR-V memory semantics is very specific to
the wording in the SPIR-V spec, which breaks its handling of OpenCL
(compared to what we had working downstream before merging upstream).

Update/relax the logic here to support CL's barrier(CLK_GLOBAL_MEM_FENCE);
