Daniel Dunbar 7f2896406c IRgen: Move the bit-field access type into CGBitFieldInfo, and change bit-field LValues to just store the base address of object containing the bit-field.

Daniel Dunbar 198bcb44b6 IRGen: Move the auxiliary data structures tracking AST -> LLVM mappings out of CodeGenTypes, to per-record CGRecordLayout structures. 
- I did a cursory check that this was perf neutral, FWIW.

Anders Carlsson a860e755f1 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.
