[clang] translate global var initializers Summary: Create dummy functions representing the initializers of global variables. This is so we can implement checks in the backend that can look at the initializer expressions of global variables. We try not to create these dummy functions when the initializer is not present, although for some reason we sometimes end up with empty initializers. Also add source file info to global variables in the backend (Pvar.re). Reviewed By: sblackshear Differential Revision: D3780238 fbshipit-source-id: 2dca87e

[SIL] change `variable_initialization()` builtin to a new auxiliary instruction Summary: Instead of emitting an ad-hoc builtin on variable declaration emit a new metadata instruction.

[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
