f3c30b7386 'noalias' needs to go on the return value, not on the function 
operand.  While I'm at it, test all the side-allocation value witnesses.

d461d72e85 Implement ErasureExpr in IR-gen, at least as far as generating 
value witnesses goes.

There are three major remaining things to do to support protocols:
  - laying out the actual protocol members
  - emitting witnesse for the actual protocol members
  - detecting uses of the actual protocol members and funnelling
    them through the witnesses as appropriate
All this work was just to let us treat protocol types as
first-class values.

6b392f8479 Turn initializeWithCopy into a generic operation on TypeInfos 
so we can optimize sub-operations properly.

ae08edf5bb Do a bit of naming cleanup in IRGen. Make sure closure IRgen doesn't get confused when we capture something other than a variable.

df7ebcd9e8 Introduce the concept of an 'owned address', i.e. an address with 
an owner attached.  Use this to implement [byref(heap)].  Force
locals to the heap if they've been referenced in a way that requires
this.

b85ddcb34a IR generation for curried functions. For now, parameters 
are stored in a malloc'ed buffer that gets leaked.

6bb1b947d8 Emit initializers of global variables as global constructors. 
This isn't the actor model for globals, but is certainly still a
valid model.

a7c7d64fa0 Switch swift to use SourceLoc instead of SMLoc. 
Also use the new getAdvancedLoc() method instead of hacking
on SMLoc directly.

Also fix the warning/note/error methods to forward through ASTContext
instead of being replicated everywhere.
