[siof] one access per sink, better report deduplication Summary: The previous domain for SIOF was duplicating some work with the generic Trace domain, and basically was a bit confused and confusing. A sink was a set of global accesses, and a state contains a set of sinks. Then the checker has to needlessly jump through hoops to normalize this set of sets of accesses into a set of accesses. The new domain has one sink = one access, as suggested by sblackshear. This simplifies a few things, and makes the dedup logic much easier: just grab the first report of the list of reports for a function. We only report on the fake procedures generated to initialise a global, and the filtering means that we keep only one report per global.

[clang] enforce that `instruction` always returns one SIL expression Summary: Previously, the type of `trans_result` contained a list of SIL expressions. However, most of the time we expect to get exactly one, and getting a different number is a soft(!) error, usually returning `-1`. This splits `trans_result` into `control`, which contains the information needed for temporary computation (hence when we don't necessarily know the return value yet), and a new version of `trans_result` that includes `control`, the previous `exps` list but replaced by a single `return` expression instead, and a couple other values that made sense to move out of `control`. This allows some flexibility in the frontend compared to enforcing exactly one return expression always: if they are not known yet we stick to `control` instead (see eg `compute_controls_to_parent`). This creates more garbage temporary identifiers, however they do not show up in the final cfg. Instead, we see that temporary IDs are now often not consecutive... The most painful complication is in the treatment of `DeclRefExpr`, which was actually returning *two* expressions: the method name and the `this` object. Now the method name is a separate (optional) field in `trans_result`. Reviewed By: mbouaziz Differential Revision: D7881088 fbshipit-source-id: 41ad3b5
