8ad5ba2428 introduce an alloc_box instruction. Also, normalize alloc_array to follow 
the syntax in SIL.rst.

fadda48e26 Switch the alloc_array instruction to return two results instead of a tuple. 
Where before we had:

  %8 = alloc_array element type=Int, %7
  %9 = tupleelement %8, 1
  %10 = tupleelement %8, 0
  %11 = type_conversion %9 -> Builtin.RawPointer
..
  %17 = apply %16(%11, %10, %7)

we now have:

  %8 = alloc_array element type=Int, %7
  %9 = type_conversion %8#1 -> Builtin.RawPointer
..
  %15 = apply %14(%9, %8#0, %7)

a2d60a1fe1 switch V->getType() uses (which are unsafe if V points to something with multiple results) to 
V.getType() which returns the type of the value being referenced.

6ab2a17518 make ValueBase::getType() take a result number, right now default it to zero in the 
base class, which is wrong.  Add shadowing versions that do allow no argument in 
derived classes where it is right.

d87f65f1a3 Land a pretty big conceptual/API change to pave the way for multiple 
return values.  Now the base class of the value hierarchy is "ValueBase"
instead of "Value", and "Value" is now a PointerIntPair indicating the
ValueBase (e.g. an instruction) being referenced along with what result
value is being referenced.

By default, any place you used "Value*" before, you should now use "Value".

4e1893236c switch the storage representation of Value::Type to be a PointerUnion<Type,TypeList*> handling 
the 0/1/N cases of types.  Still only form the "1" case though.

9967769d25 SILGen: Steal stupid cleanup support from IRGen 
Port over the basic machinery to push and pop cleanups from IRGen, and implement simple straight-line cleanup emission. Add a basic cleanup for VarDecls as a proof of concept. More sophisticated handling of outflows, dormant/alive/dead states, etc. still needs to be carried over. Breaks test/SIL/statements.swift due to lack of support for cleanups through branches.

064b2c517e SILGen: ret () instead of unreachable 
If a ()-returning function falls off the end, generate a return instead of an unreachable. IRGenFunction::emitEpilogue has some more sophisticated logic that should be ported over, but this will handle the obvious T -> () case.
