in Sema, per discussion on mailing list. This doesn't cause any changes
in the test results. I'll probably add some more tests at some point,
but it's an open question what we need to accept to be compatible with
real code.
This doesn't touch the existing isConstantExpr method on Expr; that
should be addressed somehow eventually (either removed or refined to
whatever is appropriate).

consensus was that it was fine; iso646 is trivial.
We actually don't need that many headers overall... on Ubuntu, at least,
all we need are stdint.h, stdarg.h, limits.h, and float.h to stop
depending on having gcc's headers around for normal code.
On a side note, the path searching needs some improvement; I had to
hardcode the path to my header directory into clang.cpp to get the
driver to use it consistently.

as far as I can tell, and it fixes code like test/CodeGen/functions.c.
(Whatever performance effect it might have, crashing on a
construct like this isn't really acceptable; I've run into this
multiple times.)

extend beyond the end of the function.
I'm not completely sure this is the right way to fix this bug, so
someone familiar with the parser should double-check.

Fixed a bug in ParmVarDecl::param_end(): Handle the case where there are no
ParmVarDecls for a FunctionDecl, but its function prototype has formal arguments
(can happen with typedefs).

1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST.
2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl.
3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind.
3) FunctionDecl::Destroy now releases its Body using its Destroy method.
4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors. We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes.
5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided.

implement bitfield codegen (although I don't envy the person who
implements it). This also prevents a crash on code like that from PR2309
(it's still broken, but it fails more gracefully).

they were causing bad code to be emitted. There are two fixes here: one
makes sure we emit a string that is long enough, and one makes sure we
properly handle string initialization in init lists.

used for _Bool is not the same as the primitive width (which for _Bool
is 1 bit). The load and store changes add some casts to make the
types consistent. The EmitLValue changes make sure that the pointer is
of an appropriate type for loading the bitfield.
This isn't perfect, but it's an improvement, and getting everything
right depends on actually laying out structs in an ABI-compliant way.

the condidtional have compatible types, they are not necessarily the
same type. Therefore, we cast to the composite type. As a hack, for
the moment we assume that the composite type is the type of the
left-hand expression; this isn't correct, but it's good enough for most
purposes.
