We'll need to apply the same tricks we're using for Array to Dictionary
and String, so prepare to generate base classes for those buffers as
well. Actually generate and use the one for Dictionary, but don't
actually bridge it yet.

Define a "Mirror" protocol with methods for querying the number of children a structured value has, getting the name and mirror for each of those children, and a string and "IDE representation" of the value, as needed by playgrounds and by our planned generic printing facility.
In the runtime, define a "reflect" function that can provide a Mirror for any object, either using a "Reflectable" protocol conformance if available, or falling back to a magic implementation in the runtime that grovels the type metadata. Stub out a bare minimum default implementation.

When SWIFT_OPTIMIZED is not set, add a little extra memory debugging,
which doesn't seem to slow anything down noticeably and can be disabled
as needed.
This change only affects the CMake build because that's the only place
where SWIFT_RUNTIME_CLOBBER_FREED_OBJECTS is supported already. We may
want to extend this to the Makefile build.

It'd be nice to eventually report some context information, maybe derived from the location info on the originating 'cond_fail' SIL instruction, but this is a start.
Swift SVN r9589
Add functions to dynamically query the extra inhabitants of a single-payload union's payload metadata, then identify or store bit patterns used to represent empty cases, whether they happen to use extra inhabitants or added tag bits.
