Explicitly instantiate TIntermTraverser::traverse(TIntermNode *).

(on behalf of RewriteAtomicFunctionExpressions)
The compile will occasionally choose to inline all instances of this
function, and therefore not export this entrypoint into the object file,
leaving other TUs (RewriteAtomicFunctionExpressions) with missing
link symbols.
