glsl2: Add a generic visitor class to call back with pointers to each rvalue. I keep copy and pasting this code all over, so consolidate it in one place.

* Generic class to implement the common pattern we have of wanting to
* visit each ir_rvalue * and possibly change that node to a different
* class. Just implement handle_rvalue() and you will be called with
* a pointer to each rvalue in the tree.

glsl: consistently use ifndef guards over pragma once Through the glsl headers we had an odd mix of guards be that "ifndef", "pragma once" neither or both. Simplify things by using the more common ones (ifndef) and annotating all the sources, barring the generated builting header - builtin_int64.h. The final header - udivmod64.h - is [seemingly] unused and on its way out (patch purge it is on the mailing list).
