Back out r54608 (inline string literals were getting an extra '\0')
temporarily, I assumed GetAddrForConstantString literal was being
used consistently but it doesn't look like it is.

Factored out a CodeGenModule::getStringForStringLiteral which handles
extracting a std::string for the bytes of a StringLiteral, padded to
match the type.

Update EmitLValue to use getStringForStringLiteral, this was
previously not padding strings correctly. Good thing we only emit
strings in 4 different places!

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.

Rework codegen emission of globals
- 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.

"this patch adds code generation hooks for Objective-C constant strings. It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet."

Fix and enable generating general union initializers. Essentially, what
this does is reconstruct the type for structs and arrays if the type
wouldn't be compatible otherwise.

The assertion about packing in the struct type reconstruction code
sucks, but I don't see any obvious way to fix it. Maybe we need a general
utility method to take a list of types and alignments and try to construct an
unpacked type if possible?

Some additions to constant initializer generation code. Adds
bit-field initialization; ugly code, X86-only, but it works, at least
for basic stuff. Separates/adds union initialization; currently disabled,
though, because the struct/array code needs modifications to support
elements of the wrong type.

Fixes PR2381 and PR2309 with the bit-field initialization. And NetHack
compiles and appears to work with a few tweaks (to work around the lack
of transparent_union support, and clang being a bit strict about
conflicting declarations).
