Implement C++ semantics for C-style and functional-style casts. This regresses Clang extension conversions, like vectors, but allows conversions via constructors and conversion operators.
Add custom conversions to static_cast.

Doug, please look at decltype-crash and instantiate-function-1.mm, I'm not sure
if they are actually testing the right thing / anything.

value.  This is on by default, and controlled by -Wreturn-type (-Wmost
-Wall).  I believe there should be very few false positives, though
the most interesting case would be:

  int() { bar(); }

when bar does:

  bar() { while (1) ; }

Here, we assume functions return, unless they are marked with the
noreturn attribute.  I can envision a fixit note for functions that
never return normally that don't have a noreturn attribute to add a
noreturn attribute.

If anyone spots other false positives, let me know!

2. Don't compute it if the warning isn't enabled.
3. Optimize the algorithm slightly to make it linear time in the 
case where we don't produce any warnings.

 - These kinds of "shotgun" tests are very slow, and do not belong in the
   regression suite. If these kinds of tests are regarded to have value, they
   should be added to the LLVM test-suite.

 - I would actually like to remove all of these tests, but I left Sema/carbon.c
   and SemaObjC/cocoa.m...
