Remove the filter that only irgenned SIL functions for FuncDecls so that we emit functions for all SIL decls, and disable the old paths for properties, constructors, and destructors when a SIL module is present. Unfortunately this breaks class constructors because SIL and IRGen don't agree on how initializing constructors should work. I need to sync with John to figure out how to fix that.

Implement AllocRefInst so that SIL-emitted constructors can be irgenned. Factor the code for allocating a class instance from GenClass's emitClassConstructor function.
Swift SVN r3826
Make the SIL visitor path a bit less hacky by more cleanly separating the AST walk to find types to codegen from the SIL module walk to find functions to codegen. This way, local functions and other such entry points from SIL actually get generated, and the closures test works.
Swift SVN r3820
Implement lowering of SIL ClosureInsts by packing the partial arguments into a heap allocation and emitting a thunk to unpack them and apply the closure function, similar to curried entry points. The test doesn't work quite yet because nested FuncDecls don't get visited anymore. I need to replace my hacked SIL path with a proper walk of the SIL module to generate functions and the AST to generate types.

and non-deallocating destructors and allocating/non-allocating
constructors.
Non-deallocating destructors might not play well with ObjC
classes; we might have to limit them to pure-swift hierarchies.
No functionality change except that I decided to not force
destructors to have internal linkage unconditionally.
Swift SVN r3814
Factor out the parts of GenProto's prepareExistentialMemberRefCall necessary to map to SIL's ProtocolMethodInst. Similar to ConstantRefInst, we map the ProtocolMethodInst to an incomplete CallEmission and emit the call when all curry levels have been applied.
Swift SVN r3794
Factor out the witness table initialization and projection logic from GenProto so that IRGenSIL can use it to implement the ProjectExistential and InitExistential instructions. Also map the CopyAddr and DestroyAddr instructions to value witness table calls so that value semantics on protocol values (and other address-only values) work. The added test compiles but doesn't run yet because invoking methods on a protocol value still requires implementing the ProtocolMethod instruction.
Swift SVN r3787
Implement ElementAddrInst for lvalue tuples, and implement the AllocArray, IndexAddr, and IntegerValue insts used to lower variadic tuples. (Actually compiling code that uses variadic tuples still requires support for SpecializeInst and generic functions.)
Swift SVN r3781
Implement IRGen for RefElementAddr so that class accessors work. Add a loadUnmanaged method to TypeInfo classes so that we can populate Explosions without accruing unwanted cleanups.
Swift SVN r3779
Implement ElementRefInst so that struct accessors work. Also extend SILConstant lowering to support constant_refs to constructors, destructors, and property accessors so that constructor and property accessor references work. (Constructors don't yet get visited by IRGenSIL, though.)
Swift SVN r3776
Oops, I did release but not retain. Like 'release' it currently just does emitRetainCall without checking if the type in question requires ObjC or some other future kind of memory management.
Swift SVN r3770
Implement SIL-to-IR lowering for allocation, deallocation, load, store, and branching instructions so that local variables and branching control flow can be used. Add a Fibonacci loop test to exercise the new instructions.
Swift SVN r3767
Add a path through IRGenModule to optionally codegen FuncDecls using their corresponding SIL Functions when constructed with a SILModule. Jury-rig an IRGenSILFunction subclass of IRGenFunction that does the bare minimum necessary to compile "hello world" from SIL. There are some impedance mismatches between irgen and SIL that need to be smoothed out, particularly the AST-dependent way irgen currently handles function calls. Nonetheless, `swift -sil-i hello.swift` works!
