Summary:
This makes it clearer that something went wrong. Most `failwith` did not set
this prefix already, so I opted to append it automatically and remove it from
the few instances that added it manually.
Also add quotes around bad user arguments to lessen possible confusion.

Summary:
Spacetime profiling showed that this was allocating a lot more than it needs
to. Switching to a `Hashtbl` makes the memory overhead go away, and halves the
memory consumption of the whole frontend on some pathological files.
This also brings the file "clang_ast_main.ml" into the infer repo, renamed to
"ClangPointers.ml" (and given an mli). It's useful to have something like
"clang_ast_main.ml" checked into the facebook-clang-plugins repo to illustrate
how to use the OCaml AST visitor generated by atdgen, but it can be simplified
to be more pedagogical instead of being the visitor used in infer.
