libstdc++ 4.4 uses __is_signed as an identifier, while Clang treats it
...
as a keyword for the __is_signed type trait. Cope with this conflict
via some hackish recovery: if we see a declaration of the form
static const bool __is_signed
then we stop treating __is_signed as a keyword and instead treat it as
an identifier. It's ugly, but it's better than making the __is_signed
type trait conditional on some language flag. Fixes PR9804.

Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appears
...
a bit more sinister as the memset doesn't do what the constructor does.
There seems to be a cleaner solution than a cast here though, instead we
can point the memset destination into the union its actually trying to
clear.
An alternative is to point to the Untyped member of this union. Review
appreciated, and if that is cleaner I'm happy to switch. All of these
should be functionally equivalent to the original code.

wider load would allow elimination of subsequent loads, and when the wider
load is still a native integer type. This eliminates a ton of loads on
various benchmarks involving struct fields, though it is somewhat hobbled
by clang not being very aggressive about field alignment.

Support &__uuidof(type) as a non type template argument.

This idiom is used everywhere in MFC/COM code and as such this patch removes hundreds of errors when parsing MFC code with clang.
Example:
template <class T, const GUID* g = &__uuidof(T)>
class ComTemplate { };
typedef ComTemplate<struct_with_uuid, &__uuidof(struct_with_uuid)> COM_TYPE;
Of course this is just parsing support. Trying to use this in CodeGen will generate:
