This resolves the layering violation where CodeGen depended on Frontend.

unsafe feature to use the appropriate ASTContext::getAs*ArrayType method.

Merge constant array and structures. This will create a global variables for arrays and structs that are constant and their initializer is constant. It is on by default but can be disable with the flag -fno-merge-all-constants.

Add an IsInitializer flag to EmitAnyExpr. This is used to prevent temporaries from being destroyed when they're bound to a reference variable.

 - 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?
