expressions.
 - 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?

Introduce a redecl_iterator in Decl class, so that we can do a "iterate over all declarations of the same decl" without knowing the exact type.

Introduce the Redeclarable template class, which serves as a base type defining the common interface for Decls that can be redeclared.
Make FunctionDecl and VarDecl use it.

Remove StmtLocResolver::VisitObjCIvarRefExpr, it was only there to avoid returning an implicit 'self' instead of the ivar.
Since implicit 'self' no longer has a source location, it's not needed. (plus we also want to check for a 'self' that is visible in source code)

Fix some fallout from CFGBuilder restructuring: all expressions that we explicitly handle have the possibility to be block-level expressions.
