b3b71178a5 Fix a pair of bugs with partial updates of logical l-values:
first, we weren't registering the cleanup for the temporary
if it needed materialization, and second, we were potentially
double-consuming cleanups associated with the l-value, e.g.
subscript indices.

113aa3d1ff Fix the emission of MemberRefExpr l-values and getter/setter
pairs in extensions.  The AST here is a little wierd;  I don't
really get why there needs to be a PatternBindingDecl here.
It's easy enough to ignore.

6cdecc020c Make all the subscripting getters/setters go down the same path.
This intentionally changes the mangling of variable getters and
setters so that we can have a reproducible mangling that doesn't
depend on things like the variables names, which is important
for resilience.  It's not currently important for subscripting,
although equally I see no reason to mangle in the subscript
pattern name.

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.

bc32a8aedb Fix a bug with returning value that need to be refcounted:
we want to do a take-load out of the return address slot
instead of a normal load, or else we'll end up +1'ing an

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.

5e38419345 In a currying forwarder, force the release of the data allocation
between the point at which values were loaded out and the point
at which the call is performed.  This is bad for some things,
like not spilling all the arguments, and good for others, like
not keeping the allocation around unnecessarily and being able
to do a tail call.

This has the side-effect of causing the release to actually occur,
since we're not doing cleanups yet.

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.

2b65cf22d1 Make 'this' implicitly [byref] when the container type does
not have reference semantics.  Deciding whether the container
type has reference semantics requires us to perform
some amount of limited name-binding and type-checking first,
which introduces a few complexities.

this checking right now is the inadequacy of location information
