Alexis Hunt e852b100e2 Implement a new type node, UnaryTransformType, designed to represent a
type that turns one type into another. This is used as the basis to
implement __underlying_type properly - with TypeSourceInfo and proper
behavior in the face of templates.

Argyrios Kyrtzidis 8bd428574c Add new warning that warns when invoking 'delete' on a polymorphic, non-final, class without a virtual destructor.

Douglas Gregor fcafc6e3de Implement the initial part of C++0x [expr.const]p2, which specifies
that the unevaluated subexpressions of &&, ||, and ? : are not
considered when determining whether the expression is a constant
expression. Also, turn the "used in its own initializer" warning into
a runtime-behavior warning, so that it doesn't fire when a variable is
used as part of an unevaluated subexpression of its own initializer.

Fixes PR9999.

Chandler Carruth 0dc3f8db1a Fix a bug in -Wundefined-reinterpret-cast where we failed to look
through sugared types when testing for TagTypes. This was the actual
cause of the only false positive in Clang+LLVM.

Next evaluation will be over a much larger selection of code including
large amounts of open source code.

Alexis Hunt 6a31f2c7c9 Delete the extraneous return statement that was causing my earlier
issues and also add a test.

We should now handle defaulted members of templates properly. No
comment as to whether or not this also holds for templated functions,
but defaulting those is kind of insane.

Alexis Hunt 1fb4e76218 Correctly propagate defaultedness across template instantiation. This
fixes PR9965, but we're not out of the water yet, as we do not
successfully handle out-of-line definitions, due to my utter
misunderstanding of how we manage templates.

Francois Pichet efb1af9ae8 Emulate a MSVC bug where if during an using declaration name lookup, the declaration found is unaccessible (private) and that declaration was bring into scope via another using declaration whose target declaration is accessible (public) then no error is generated.
Example:
class A { public: int f();  };
class B : public A { private: using A::f; };
class C : public B { private: using B::f; };

Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it.

This fixes 1 error when parsing MFC code with clang.

Chris Lattner e76b95ae15 make the x86-32 backend specify a byval alignment, even when the

Chris Lattner 44c2b90556 Fix x86-64 byval passing to specify the alignment even when the code
generator will give it something sufficient.  This is important because
the mid-level optimizer doesn't know what alignment is required otherwise.

Chris Lattner 3bdc7679ce Invoke the FileChanged callback before pushing the linemarker for a system
header.  Getting it in the wrong order generated incorrect line markers in -E 
mode.  In the testcase from PR9861 we used to generate:

# 1 "test.c" 2
# 1 "./foobar.h" 1
# 0 "./foobar.h"
# 0 "./foobar.h" 3
# 2 "test.c" 2

now we properly produce:

# 1 "test.c" 2
# 1 "./foobar.h" 1
# 1 "./foobar.h" 3
# 2 "test.c" 2

This fixes PR9861.

Douglas Gregor 80af31397a Audit and finish the implementation of C++0x nullptr, fixing two
minor issues along the way:
  - Non-type template parameters of type 'std::nullptr_t' were not
  permitted.
  - We didn't properly introduce built-in operators for nullptr ==,
  !=, <, <=, >=, or > as candidate functions .

To my knowledge, there's only one (minor but annoying) part of nullptr
that hasn't been implemented: catching a thrown 'nullptr' as a pointer
or pointer-to-member, per C++0x [except.handle]p4.

Douglas Gregor 347e0f26be Fix our handling of the warning when one tries to pass a
non-POD/non-trivial object throuugh a C-style varargs. The warning
itself was default-mapped to error, but can be downgraded, but we were
treating it in Sema like a hard error, silently dropping the call.

Instead, treat this problem like a warning, and do what the warning
says we do: abort at runtime. To do so, we fake up a __builtin_trap()
expression that gets evaluated as part of the argument.

prints the file, line, and column of a diagnostic. We currently
support Clang's normal format, MSVC, and Vi formats.

Note that we no longer change the diagnostic format based on
-fms-extensions.

Type::isUnsignedIntegerOrEnumerationType(), which are like
Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also

Audited all callers to the existing functions, switching those that
need to also handle scoped enumeration types (e.g., those that deal
with constant values) over to the new functions. Fixes PR9923 /

Alexis Hunt e77a28f7e1 Implement an additional fix for infinite recursion of deleted special
member functions by making sure that they're on the record before
checking for deletion.

Also make sure source locations are valid to avoid crashes.

Unfortunately, the declare-all-implicit-members approach is still
required in order to ensure that dependency loops do not result in
incorrectly deleting functions (since they are to be deleted at the
declaration point per the standard).
