Summary:
Before: `make clean` followed by running `infer -- make`. If infer fails, it is
rerun automatically (by the `silent_on_success` Makefile function) to show the
output to the user, but by then there is nothing to build and `make` does
nothing.
Now: run directly `infer -- make clean all`. If infer fails, the command is
rerun and rebuilds all the source files, so there is a higher chance that the
same error will be displayed to the user than the one that originally caused
the command to fail.

Summary:
A good first step in order to run multiple checkers together is to prevent the analysis the analysis to side effect on the summaries of the method being analyzed from disk, or the shared specs summary. The idea is that `Ondemand` creates a summary for the procedure being analyzed and only saves the summary once all the checkers have been run. The summary for the caller (i.e. the procedure being analyzed) should never be looked up from disk during the analysis. In other words, the analysis should only ever lookup the summaries of the callees and the proposed solution to enforce this is to have `Ondemand.analyze_proc_name` be the only way to lookup the summary of a procedure.
Another objective is to make sure that the summaries are never saved to disk more than once.

Summary:
We waste a lot of space storing the types of field accesses and comparing them sets/maps with access paths.
Yet almost none of the code ever looks at these types (only a tiny piece of code in thread-safety).
If we know the base type, we have enough information to recover the type of the field.
Let's do that instead.

This simplifies a bit the code to run the analysis on all the prcedures in the cluster. Before, the functions procedure_should_be_analyzed, which loads the attributes, and get_proc_desc were called twice for the analysis of every procedure.
The objective is to remove the calls to procedure_should_be_analyzed and hide it from the ondemand API since it is already called before the analysis of every procedure.
