spirv: Add a workaround for OpControlBarrier on old GLSLang

As per the Vulkan memory model, the proper translation of GLSL barrier()
is an OpControlBarrier with a scope of Workgroup and semantics of
Acquire, Release, and WorkgroupMemory.  Older versions of GLSLang gave
an OpControlBarrier with semantics of None so we need to patch it up on
those versions.
