Summary:
Fixes problems that lead to incorrect formatting of these and similar snippets:
/*
 **
 */

/*
 **/

/*
 * */

/*
 *test
 */

Clang-format used to think that all the cases above use "* " decoration, and
failed to calculate insertion position properly. It also used to remove leading 
"* " in the last line.

This is mostly Doxygen formatting, but also updates some C++0x references
to C++11 and clarifies some wording.

Sema::MergeFunctionDecl attempts merging two decls even if the old decl
is invalid.  This can lead to interesting circumstances where we
successfully merge the decls but the result makes no sense.

Take the following for example:

template <typename T>
int main(void);

int main(void);

Sema will not consider these to be overloads of the same name because
main can't be overloaded, which means that this must be a redeclaration.

In this case the templated decl is compatible with the non-templated
decl allowing the Sema::CheckFunctionDeclaration machinery to move on
and do bizarre things like setting the previous decl of a non-templated
decl to a templated decl!

The way I see it, we should just bail from MergeFunctionDecl if the old
decl is invalid.

This fixes PR16531.

This boils down to us sending invalid function decls to
CheckFunctionDeclaration becauswe we did not consider that CheckMain
could cause the decl to be invalid.  Instead, interogate the new decl's
main-validity and *then* send it over to get CheckFunctionDeclaration'd
if it was still valid after calling CheckMain.

This changes the TBAA code so it doesn't use mangleCXXRTTIName in C,
because it doesn't really make sense there.  Also, as sort of a
defense-in-depth change, fix the mangler so it handles C RecordDecls
correctly.

No tests because I don't know the TBAA code well enough to write a test,
and I don't know how else to trigger mangling a local struct in C.

Fixes a crash with r185450 reported by Joerg Sonnenberger.

As it turns out, the NoFunction bit for local class mangling needed to be
propagated into more places. r185450 turned what used to be an incorrect
mangling into an assertion.

We should not be asking unique_file to prepend the system temporary directory
when creating the html report. Unfortunately I don't think we can test this
with the current infrastructure since unique_file ignores MakeAbsolute if the
directory is already absolute and the paths provided by lit are.

I will take a quick look at making this api a bit less error prone.

This is a better implementation of r183097. The main purpose is to
prevent certain constructs to be formatted "like a block of text".

Before:
aaaaaaaaaaaaa<
    aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa = new aaaaaaaaaaaaa<
    aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] = (*cccccccccccccccc)[
    dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];

After:
aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
              aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
              aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa =
    new aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
                      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(
        bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] =
    (*cccccccccccccccc)[
        dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];

Additionally, allow breaking after c-style casts, but with a high
penalty.

Before:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (
    aaaaaaaaaaaaaaaaa *)bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
After:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (aaaaaaaaaaaaaaaaa *)
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
