I'm not surprised.  The --dump-builder option of the stand-alone compiler was added to support generating int64 lowering functions from GLSL.  I had no expectation that anyone would use that option for anything else.

I would also not be surprised if there were a bunch of other things that didn't work.  Unless we have use cases, I don't know if there's a lot of value in fixing these issues.  I will also reply to your MR (https://gitlab.freedesktop.org/mesa/mesa/merge_requests/201/diffs).
