Douglas Gregor d7fb85e8ad Reimplement the handling of the "current object" in designator
initializers, so that we are within the appropriate subobject after
we've processed a multi-designator designation. We're matching GCC and
EDG's behavior on all examples I've found thus far.

*Huge* thanks to Eli Friedman for pointing out my fundamental
misunderstanding of "current object" in the C99 spec.

Douglas Gregor e4a0bb7a20 Initial implementation of semantic analysis and ASTs for C99
designated initializers. This implementation should cover all of the
constraints in C99 6.7.8, including long, complex designations and
computing the size of incomplete array types initialized with a
designated initializer. Please see the new test-case and holler if you
find cases where this doesn't work.

There are still some wrinkles with GNU's anonymous structs and
anonymous unions (it isn't clear how these should work; we'll just
follow GCC's lead) and with designated initializers for the members of a
union. I'll tackle those very soon.

CodeGen is still nonexistent, and there's some leftover code in the
parser's representation of designators that I'll also need to clean up.
