Fix handling of C++ references Summary: @​public This diff changes following things: 1. expression_info.type_ptr has type than decl_ref_info.type_ptr for reference types. Use type from decl_ref_info as a source of truth 2. reference types need to have one extra dereference that is not in AST. Add handling for this. 3. [small refactor] create function that creates temporary variable from res_trans expression and returns new res_trans. Some caveats: 1. types are not quite right yet (see .dot files). 2. decl_ref_info might not be set for DeclRefExpr, make frontend crash in that case to catch when this happens This is high risk change since it changes behavior of every translation on very widely used expr.

[preanalysis] do not delay killing variables taken by reference Summary: Before, the liveness pre-analysis would place extra instructions in the CFG for either: 1. marking an `Ident.t` as dead, or 2. marking a `Pvar.t` as `= 0` But we have no way of marking pvars dead without setting them to 0. This is bad because setting pvars to 0 is not possible everywhere they are dead. Indeed, we only do it when we haven't seen their address being taken anyway. This prevents the following situation, recorded in our tests: ``` int address_taken() { int** x; int* y; int i = 7; y = &i; x = &y; // if we don't reason about taken addresses while adding nullify instructions, // we'll add // `nullify(y)` here and report a false NPE on the next line return **x; } ``` So we want to mark pvars as dead without nullifying them. This diff extends the `Remove_temps` SIL instruction to accept pvars as well, and so renames it to `ExitScope`. Reviewed By: da319 Differential Revision: D13102953 fbshipit-source-id: aa7f03a52
