Summary: public First in a series of diffs fixing the __nullable checker for obj-c, which currently reports false positives on property accesses via getters and setters. To fix this problem, we need a special implementation of letderef and set for property accesses that don't report NPE errors. Factoring out the execution of these instructions from the main symbolic executor will make this easier.

The instructions to install opam from the web on linux were not enough:
you need to install opam somewhere on the PATH. Moreover, the wget
command could erase "opam" if launched from the infer repo, which
already has an "opam" file.
./build-infer.sh's "opam init" command would fail if ocaml was not already
installed, instead of installing a default compiler.
Finally, check that ocamlfind is installed using the same logic as other
ocamlfind packages, to get an error message explaining how to get it
using opam if it's not installed, instead of just a failure.
