caused us to skip layout out a function accurately. If
so, flush the type cache for both the function and struct
case to ensure that any pointers to the functions get
recomputed. This is overconservative, but with this patch
clang can build itself again.

conservative when converting a functiontype to IR when in a "pointer within
a struct" context. This has the unfortunate sideeffect of compiling all
function pointers inside of structs into "{}*" which, though correct, is
ugly. This has the positive side effect of being correct, and it is pretty
straight-forward to improve on this.

- Emit default-initialization of arrays that were partially initialized
with initializer lists with a loop, rather than emitting the default
initializer N times;
- support destroying VLAs of non-trivial type, although this is not
yet exposed to users; and
- support the partial destruction of arrays initialized with
initializer lists when an initializer throws an exception.

where we have an immediate need of a retained value.
As an exception, don't do this when the call is made as the immediate
operand of a __bridge retain. This is more in the way of a workaround
than an actual guarantee, so it's acceptable to be brittle here.

structure to hold inferred information, then propagate each invididual
bit down to -cc1. Separate the bits of "supports weak" and "has a native
ARC runtime"; make the latter a CodeGenOption.
The tool chain is still driving this decision, because it's the place that
has the required deployment target information on Darwin, but at least it's
better-factored now.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.
