glsl: Fix variable_referenced() for vector_{extract,insert} expressions
We get these when we operate on vector variables with array accessors (i.e. things like a[0] where 'a' is a vec4). When we call variable_referenced() on these expressions we want to return a reference to 'a' instead of NULL. This fixes a problem where we pass a[0] as the first argument to an atomic SSBO function that expects a buffer variable. In order to check this, we use variable_referenced(), but that is currently returning NULL in this case, since the underlying rvalue is a vector_extract expression.
