 - Steve, can you take a look at this? It seems like this code should live
   elsewhere, and there is a FIXME about having Sema validates the UTF-8 to
   UTF-16 conversion.

We don't need to keep track of the packed alignment, just whether the struct is packed or not. Fixes PR4610.

Move the LLVM field number for bit fields into the BitFieldInfo structure, since it's meaning is completely different than for non-bit fields.

Use arrays as union padding. Also, since the resulting struct will always contain a single element and either a single i8 element or an array of i8s, there's no reason to use a packed struct.

Check in  CGRecordLayoutBuilder which is a reimplementation of the record layout code. (Yay, no more packed structs unless absolutely necessary). We currently don't use the layouts being built but that will change when the new code is mature enough :)

Technically we could still do a bit more to avoid deferred generation of statics
which we know are used, but I seriously doubt this is important.

This requires llvm rev. 76769 or higher.

Fix a couple recent ABI regressions noticed during code review (fallout from the ObjC type system rewrite).

It's unfortunate that the mangling includes the low-level structs. Nevertheless, we need this for binary compatibility with GCC.

 - This generally catches the important case of noreturn functions.

 - With the last two changes, we are down to 152 unreachable blocks emitted on
   403.gcc, vs the 1805 we started with.

 - Emit variable declarations as "simple", we want to avoid forcing the creation
   of a dummy basic block, but still need to make the variable available for
   later use.

 - With that, we can now skip IRgen for other unreachable statements (which
   don't define a label).

 - Anders, I added two fixmes on calls to EmitVLASize, can you check them?
