Summary:
Use jbuilder to build infer instead of ocamlbuild. This is mainly to get faster builds:

Menu:

1. Write a jbuild file, autogenerated from jbuild.in because we need to fill in
  some information at build-time (really, at configure time, but TODO), such as
  whether or not clang is enabled.
2. Nuke lots of stuff from infer/src/Makefile that is now in the jbuild file
3. The jbuild file lives in infer/src/ so it can see all the sources. If we put it somewhere else, eg, infer/, then `jbuilder` scans too many files (all irrelevant) and takes 2.5s to start instead of .8s. Adding irrelevant directories to jbuild-ignore does not help.
4. jbuilder does not support subdirectories, so resort to listing all the
  source files in the generated jbuild (only source directories need to be
  manually listed in jbuild.in though). Still, the generated .merlin is wrong
  and makes merlin find source files in _build, so manually tune it to get
  good merlin support. We also lose some of merlin for unit tests as it
  cannot see their build artefacts anymore.
5. checkCopyright gets its own jbuild because it's standalone. Also, remove
  some deprecation warnings in checkCopyright due to the new version of Core from
  a while ago.
6. Drop less-used Makefile features (they had regressed anyway) such as
  building individual modules. Also, building mod_dep.pdf now takes all the
  source files available so they better build (before, it would only take the
  source files from the config, eg with or without clang) (that's pretty minor).
7. The toplevel is now built as a custom toplevel because that was easier. It
  should soon be even easier: https://github.com/janestreet/jbuilder/issues/210
8. Move BUILTINS.mli to BUILTINS.ml because jbuilder is not happy about
  interface files without implementations.

In particular, I did not try to migrate too much of the Makefile logic to jbuilder,
more can be done in the future.
