 - Follows emission scheme used by llvm-gcc, i.e. invent an id for
   each label whose address is taken and replace each indirect goto by
   a switch to each possible target.
 - Currently we emit a switch for each indirect goto instead of
   merging them as llvm-gcc does.

Finally fix PR2189.  This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

 - There is an miscompilation issue remaining due to a poor
   interaction between the delayed emission of static functions and
   the emission of constructors, but that already existed prior to
   this change.

instead of mapping the decl to a bitcast of the global to the correct
type.
 
 - GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now.

 - This solves a problem where a dangling pointer could be introduced
   by the RAUW done when replacing a forward or tentative
   definition. See testcase for more details.

 - Fixes <rdar://problem/6108358>

 - No (intended) functionality change.

 - Primary purpose is to clearly separate (lazy) construction of
   globals that are a forward declaration or tentative definition from
   those that are the final definition.

 - Lazy construction is now encapsulated in
   GetAddrOf{Function,GlobalVar} while final definitions are
   constructed in EmitGlobal{Function,Var}Definition.
 
 - External interface for dealing with globals is now limited to
   EmitGlobal and GetAddrOf{Function,GlobalVar}.

 - Also updated helper functions dealing with statics, annotations,
   and ctors to be private.

 - Fix multiple issues with the way case ranges were emitted, see test
   cases details about the specific issues.

 - The root issue was not being careful about how basic blocks were
   emitted which led to them being chained together incorrectly,
   resulting in improper control flow.

 - Fixes <rdar://problem/6098585>

llvm-svn: 54006

 - Also cleaned up emission slightly 
 - Inspection of the code revealed several other bugs, however. Case
   ranges are not properly wired and can result in switch cases being
   dropped or even infinite loops. See: <rdar://problem/6098585>
