94244131f7 Remove ElementRefDecl and DeclVarName. Add the replacement, PatternBindingDecl. Use proper pattern parsing for variable declarations. Uniformly use PatternBindingDecl for variable initialization. Adapt type-checking and IRGen for this new style of variable declaration. <rdar://problem/11124980>.

173d750a02 Switch IR-generation to use ASTVisitor, or more precisely, to 
use irgen::ASTVisitor, which is a subclass of the AST version
that always looks through some expressions and asserts that
others (the unchecked/error ones) can't happen.  The main
obstacle to that is access control, because it's quite nice to
have the visitor be a non-local class for nesting purposes,
but that makes it impossible to use private methods anymore.
It's nice to give all the type-specific emitters private
interfaces anyway, though;  that ends up being most of the
patch.

I futzed with GenClosure.cpp while I was in there, but
separating it would have been obnoxious.

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.

2fd608ae4d Add basic parsing and type-system support for the byref(heap) 
qualifier, making sure that variables end up so-qualified by
default.  Add a RequalifyExpr to capture the act of adding
qualifiers (to form a supertype) to an l-value.

c7bcadf450 On further reflection and use, the concept of an RValue is not actually 
very useful;  it is much more interesting to divide r-value emission
into "to arguments" and "to memory" models.  To that end, introduce a
new structure for holding an "exploded" r-value.

066719530c Implement rudimentary l-value and r-value emission for DeclRefExpr. 
Swift's ASTs are lacking the extremely useful concept of a DeclContext,
without which it's probably possible to make this work, but it'll be
extremely awkward.  Anyway, these hacks are good enough to get the
test passing again.
