A semi-gross fix for a debug info issue. When inserting the "function start" label (i.e. first label in the entry block) take care to insert it at the beginning of the block.

Even though InsertAtEndOfBasicBlock is an ugly hack it still deserves a proper name. Rename it to EmitInstrWithCustomInserter since it does not necessarily insert
instruction at the end.

this, it should come up with a consistent AST.

- Expand tabs... (poss 80-col violations, will get them later...)
- Consolidate logic for SelectDFormAddr and SelectDForm2Addr into a single
  function, simplifying maintenance. Also reduced custom instruction
  generation for SPUvecinsert/INSERT_MASK.

Many refinements to Sema::MergeVarDecl(). This routine still needs some re-work to fully handle tentative decls.

This includes a fix to bz1908.

In practice this can only happen on code with already undefined behavior, 
but this is still a good thing to handle correctly.

functions getLoadedVT and getStoredVT are replaced with the common
getMemoryVT to simplify code that will handle both loads and stores.

did not explicitly do so (i.e., we just propagate the current state).

- Some minor optimizations of the encoding format for ObjCAtSynchronizedStmt.
- Reordered methods so that the deserialization methods for 
  ObjCAtSynchronizedStmt appear in alphabetical order with the corresponding
  methods of the other AST nodes.
