themselves have no template parameters. This is actually a restriction
due to the grammar of template template parameters, but we choose to
diagnose it in Sema to provide better recovery.

redeclarations of main appropriately rather than allowing it to be
overloaded. Also, disallowing declaring main as a template.

nil. Otherwise we can get false paths where a second @synchronized using the mutex

entities in the preprocessing record. Previously, we would only end up
getting the first token of a preprocessing record annotated
correctly. For example, given
#include "foo.h"
we would only get the '#' annotated as an inclusion directive; the
'include' and '"foo.h"' tokens would be given the general 'processing
directive' annotation.
Now, we get proper annotations for entities in the preprocessing
record.

This adds an option to set the _MSC_VER macro without
recompiling. This is very useful when testing compatibility
with the Windows SDK and c++stdlib headers.

inclusion directives, keeping track of every #include, #import,
etc. in the translation unit. We keep track of the source location and
kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

FunctionType! I didn't realize it was available, until rjmccall
pointed out that DeclaratorDecl made the typeloc available. This
makes FunctionDecl recursion *much* easier, because the typeloc can
take care of default parameters, so we no longer have to do that
separately, which means we can just do a normal type traversal instead
of this special-case WalkUp stuff we did before.
The only downside -- and it's minor -- is that because the TypeLoc
handles both the return type and the argument types, we can't recurse
on the explicit template args in the right place (which would be
between them). I do it beforehand instead. So for
int MyFunc<float>(char x);
we get callbacks in the order: float, int, char.

As far as I can see, gcc is right to think this! The following change
will cause a nice segfault rather than undefined behaviour if this case
occurs. Someone who understands what this code is supposed to do should
probably take a proper look.

don't repeatedly loop through identifiers, correcting the same typo'd
identifier over and over again.
We still bail out after 20 typo corrections, but this should help
improve performance in the common case where we're typo-correcting
because the user forgot to include a header.

Here's example code:
---
template<class T> class MyClass {
struct S { };
S* NewS() { return new S; }
void DeleteS() { delete NewS(); }
};
---
CXXDeleteExpr::getDestroyedType() on the 'delete NewS()' expression
would crash before this change. Now it returns a dependent type
object. Solution suggested by dgregor.
