Add C++ include paths for libstdc++ with Ubuntu 11.04 and Debian's libstdc++6-4.5, as collected from http://packages.ubuntu.com/search?mode=exactfilename&suite=natty&section=all&arch=any&searchon=contents&keywords=c%2B%2Blocale.h and http://packages.debian.org/wheezy/armel/libstdc++6-4.5-dev/filelist
Fixes compilation with clang++ on Ubuntu 11.04.

This is more efficient as it's all done at once at the end of the TU.
This could still get expensive, so a flag is provided to disable it. As
an added bonus, the diagnostics will now print out a cycle.

The PCH test is XFAILed because we currently can't deal with a note
emitted in the header and I, being tired, see no other way to verify the
serialization of delegating constructors. We should probably address
this problem /somehow/ but no good solution comes to mind.

if they're template template parameters applied to template arguments).

tag, filter out those ambiguous names that we found if they aren't
within the declaration context where this newly-defined tag will be
visible.

This is basically a hack, because we really need to fix the lookup of
tag declarations in this case to not find things it
shouldn't. However, it's better than what we had before, and it fixes
<rdar://problem/9168556>.

This means that the delegating constructor implementation should be
complete and correct, though there are some rough edges (diagnostic
quality with the cycle detection and using a deleted destructor).

Material bugfixes to come this afternoon.

parameters on the floor in certain cases:
class X {
  template <typename T> friend typename A<T>::Foo;
};

This was parsed as a *non* template friend declaration some how, and
received an ExtWarn. Fixing the parser to actually provide the template
parameters to the freestanding declaration parse triggers the code which
specifically looks for such constructs and hard errors on them.

Along the way, this prevents us from trying to instantiate constructs
like the above inside of a outer template. This is important as loosing
the template parameters means we don't have a well formed declaration
and template instantiation will be unable to rebuild the AST. That fixes
a crash in the GCC test suite.

Added an assert to IntegerLiteral to ensure that the integer type passed in has the same size as the APInt passed in.  Also, updated the comments around IntegerLiteral.

Changed the integer type that range-based for-loops used.  Switched to pointer difference type, which satisfies the new assert in IntegerLiteral.

-Wundefined-reinterpret-cast, and I think a reasonable case for it to
warn on.

Also use is<...> instead of dyn_cast<...> when the result isn't needed.

This whole thing should probably switch to using UsuallyTinyPtrVector.
