Rename DeclContext::getLookupContext to getRedeclContext and change its semantics slightly. No functionality change in the absence of inline namespaces. Also, change a few places where inline namespaces actually make a difference to be prepared for them.

When instantiating a function type, instantiate the return type before
instantiating the parameters. In a perfect world, this wouldn't
matter, and compilers are free to instantiate in any order they
want. However, every other compiler seems to instantiate the return
type first, and some code (in this case, Boost.Polygon) depends on
this and SFINAE to avoid instantiating something that shouldn't be
instantiated.
We could fight this battle, and insist that Clang is allowed to do
what it does, but it's not beneficial: it's more predictable to
instantiate this way, in source order. When we implement
late-specified return types, we'll need to instantiate the return type
last when it was late-specified, hence the FIXME.

Improve code completion for initializer lists in constructors. Instead
of prioritizing just by initialization order, we bump the priority of

we'll still get ordered completion for the rest.
