```
Sema: eliminate `src` field

`sema.src` is a failed experiment. It introduces complexity, and makes
often unwarranted assumptions about the existence of instructions
providing source locations, requiring an unreasonable amount of caution
in AstGen for correctness. Eliminating it simplifies the whole frontend.

This required adding source locations to a few instructions, but the
cost in ZIR bytes should be counteracted by the other work on this
branch.
