Introduce a new PragmaPack attribute, and use it for #pragma pack. The PackedAttr now only represents __attribute__((packed)).

This is necessary because #pragma pack and __attribute__((packed)) have different semantics. No functionality change yet, but this lays the groundwork for fixing a record layout bug.

Enable the new struct type builder now that the constant struct builder works. (The old code will still be there until we know that everything works well.

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.

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 :)
