Use arrays as union padding. Also, since the resulting struct will always contain a single element and either a single i8 element or an array of i8s, there's no reason to use a packed struct.

Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methods
until Doug Gregor's Type smart pointer code lands (or more discussion occurs).
These methods just call the new Type::getAs<XXX> methods, so we still have
reduced implementation redundancy. Having explicit getAsXXXType() methods makes
it easier to set breakpoints in the debugger.

PR4390: Make sure to handle anonymous unions correctly while building
static intializers for structs.

Sink the BuiltinInfo object from ASTContext into the
preprocessor and initialize it early in clang-cc. This
ensures that __has_builtin works in all modes, not just
when ASTContext is around.

push GlobalDecl through enough of the CodeGenModule interfaces
to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in
member-functions.

It looks like codegen isn't emitting a call to the dtor in
member-functions.cpp:test2, but when it does, its body should
get emitted.

Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change.

Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).
