Add a path through IRGenModule to optionally codegen FuncDecls using their corresponding SIL Functions when constructed with a SILModule. Jury-rig an IRGenSILFunction subclass of IRGenFunction that does the bare minimum necessary to compile "hello world" from SIL. There are some impedance mismatches between irgen and SIL that need to be smoothed out, particularly the AST-dependent way irgen currently handles function calls. Nonetheless, `swift -sil-i hello.swift` works!

a lot closer to successfully emitting the polymorphic-min-over-ranges
example; the main blocker right now seems to be that the witness
for a static member function is not, in fact, a static member
function at al, but a freestanding function. That's legitimate,
but it probably needs some shepherding through the witness
system.

by abstraction from the concrete return type.
This basically gets generic calls working totally as long
as there's no remapping required.

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.

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.
