chosen by examining the class, selecting the smallest representation
that would work given the class definition or lack thereof).

[LPM] A terribly simple fix to a terribly complex bug: PR18773.
The crux of the issue is that LCSSA doesn't preserve stateful alias
analyses. Before r200067, LICM didn't cause LCSSA to run in the LTO pass
manager, where LICM runs essentially without any of the other loop
passes. As a consequence the globalmodref-aa pass run before that loop
pass manager was able to survive the loop pass manager and be used by
DSE to eliminate stores in the function called from the loop body in
Adobe-C++/loop_unroll (and similar patterns in other benchmarks).
When LICM was taught to preserve LCSSA it had to require it as well.
This caused it to be run in the loop pass manager and because it did not
preserve AA, the stateful AA was lost. Most of LLVM's AA isn't stateful
and so this didn't manifest in most cases. Also, in most cases LCSSA was
already running, and so there was no interesting change.
The real kicker is that LCSSA by its definition (injecting PHI nodes
only) trivially preserves AA! All we need to do is mark it, and then
everything goes back to working as intended. It probably was blocking
some other weird cases of stateful AA but the only one I have is
a 1000-line IR test case from loop_unroll, so I don't really have a good
test case here.
Hopefully this fixes the regressions on performance that have been seen
since that revision.

Improve diagnostic for using non-class/namespace/scoped enum in a nested name specifier.
Rather than simply saying "X is not a class or namespace", clarify what
X is by providing the aka type in the case where X is a type, or
pointing to the named declaration if there's an unambiguous one to refer
to. In the ambiguous case, the ambiguities are already enumerated
(though could be clarified by describing what kind of entities they are)
Included a few FIXMEs in tests where some further improvements could be
made.

[docs] TableGen easter egg: Multiline string literals
They're called code fragments, but they are really multiline string
literals. Just spotted this usage in a patch by Aaron using "code
fragments" for holding documentation text. I remember someone bemoaning
the lack of multiline string literals in TableGen, so I'm explicitly
documenting that code fragments are multiline string literals.
Let it be known that any use case needing multiline string literals in
TableGen (such as descriptions of options, or whatnot) can use use
code fragments (instead of C-style string concatenation or exceedingly
long lines). E.g.
class Bar<int n>;
class Baz<int n>;
class Doc<string desc> {
string Desc = desc;
}
def Foo : Bar<1>, Baz<3>, Doc<[{
This Foo is a Bar, and also a Baz. It can take 3 values:
* Qux
* Quux
* Quuux
}]>;

LoopVectorizer: Keep track of conditional store basic blocks
Before conditional store vectorization/unrolling we had only one
vectorized/unrolled basic block. After adding support for conditional store
vectorization this will not only be one block but multiple basic blocks. The
last block would have the back-edge. I updated the code to use a vector of basic
blocks instead of a single basic block and fixed the users to use the last entry
in this vector. But, I forgot to add the basic blocks to this vector!

Move the -fms-compatibility using decl check after real access checking
Summary:
This avoids false positives from -Wmicrosoft when name lookup would
normally succeed in standard C++. This triggered on a common CRTP
pattern in clang, where a derived class would have a private using decl
to pull in members of a dependent base:
class Verifier : InstVisitor<Verifier> {
private:
using InstVisitor<Verifier>::visit;
...
void anything() {
visit(); // warned here
}
};
Real access checks pass here because we're in the context of the
Verifier, but the -Wmicrosoft extension was just looking for the private
access specifier.
