b7130ed888 Enable the new constant struct builder by default. The old code is still in place but will be removed shortly. The new struct builder works on big endian systems.

718a89a501 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.

8a286fbdb9 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.

cfbfe78e9e De-ASTContext-ify DeclContext. 
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

e0be0dfced 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.cpp:test2, but when it does, its body should
get emitted.

66afeb5968 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).

d7e7b8e411 first wave of fixes for @encode sema support. This is part of PR3648. 
The big difference here is that (like string literal) @encode has 
array type, not pointer type.

a67033294a Add enough checking to ensure that non-constant block literals don't 
appear to be constant.  I'll probably redo this and throw it all away
later once we have codegen for BlockDeclRefExprs.

18e1444f82 Remove IRgen constant emission assumption that LValue APValue results 
only occur for pointer types; they are also possible for integer types
now.
 - No intended functionality change, IntExprEvaluate doesn't return
   LValue results yet.

38ad1e6138 Change EmitConstantExpr to allow failure. 
IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.

e711f7052e Add hook to add attributes to function declarations that we know 
about, whether they are builtins or not. Use this to add the
appropriate "format" attribute to NSLog, NSLogv, asprintf, and
vasprintf, and to translate builtin attributes (from Builtins.def)
into actual attributes on the function declaration.

Use the "printf" format attribute on function declarations to
determine whether we should do format string checking, rather than
looking at an ad hoc list of builtins and "known" function names.

Be a bit more careful about when we consider a function a "builtin" in
C++.
