2e8733054e Hack fast implementations of '&&' and '||' into IRGen.

0241d0ec20 Implement IRGen for local function decls. Known limitations at the moment: currying is unimplemented, and capturing the decl is unimplemented.

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.

e1b8daa717 Rework 'foreach' AST to reflect how IRgen actually wants it to look, 
rather than how I felt like generating it.

85fecab3b1 Reorganize the emission of a call site so that it's abstracted over 
exactly how the arguments are emitted.  Introduce a new code path
which emits arguments from existing Explosions (possibly of the wrong
resilience level).  Use that code path to implement getter/setter
code for MemberRefExpr l-values.  This is just a checkpoint for the
latter two parts, but the ApplyExpr path is working correctly in the
new framework, which is worth a commit.

f3e27d90ff Change IR-generation so that it emits metadata objects for the 
heap allocations it makes, and switch swift_alloc over to pass
that pointer in as well as the alignment.  Also, compute
whether a type is POD during its generation and cache that in
the object, and introduce a method on TypeInfo to destroy an
object in memory.

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.
