The TargetPassManager's default constructor wants to initialize the PassManager
to 'null'. But it's illegal to bind a null reference to a null l-value. Make the
ivar a pointer instead.

- There's no point having a different type for the local and global symbol
tables.
- Renamed SymbolTable to GlobalSymbolTable to clarify the intention
- Improved const correctness where relevant

and only consider using __cxa_atexit in the Itanium logic. The
default logic is to use atexit().
Emit "guarded" initializers in Microsoft mode unconditionally.
This is definitely not correct, but it's closer to correct than
just not emitting the initializer.

I broke this in r155838 by not actually instantiating non-dependent default arg
expressions. The motivation for that change was to avoid producing duplicate
conversion warnings for such default args (we produce them once when we parse
the template - there's no need to produce them at each instantiation) but
without actually instantiating the default arg, things break in weird ways.
Technically, I think we could still get the right diagnostic experience without
the bugs if we instantiated the non-dependent args (for non-dependent params
only) immediately, rather than lazily. But I'm not sure if such a refactoring/
change would be desirable so here's the conservative fix for now.

what I'm going to treat as basically universal properties of
array-cookie code. Implement MS array cookies on top of that.

Similar to r155808 - this mistake has been made in a few iterators.
Based on Chandler Carruth's feedback to r155808 I added an implicit conversion
to Decl* to ease adoption/usage. Useful for the pointer comparison, but not the
dyn_cast (due to template argument deduction causing the conversion not to be
used) - there for future convenience, though. This idiom (op T* for iterators)
seems to be fairly idiomatic within the LLVM codebase & I'll likely add it as I
fix up the other iterators here.

This is a second attempt at a fix for this, the first was r155468. Thanks
to Chandler, Bob and others for the feedback that helped me improve this.

being used in an exception specification in a way which isn't otherwise
ill-formed in C++98: this warning also incorrectly triggered on uses of 'this'
inside thread-safety attributes, and the mechanism required to tell these cases
apart is more complex than can be justified by the (minimal) value of this part
of -Wc++98-compat.

of a local variable, make sure we don't infinitely recurse when the
reference binds to itself.
e.g:
int* func() {
int& i = i; // assign non-exist variable to a reference which has same name.
return &i; // return pointer
}

Replace some assert() calls w/ actual diagnostics. In a perfect world,
there'd be range checks on these values long before things ever reached
this code. For now, though, issuing a better-late-than-never diagnostic
is still a big improvement over assert().

calculating it recursively.
boost::assign::tuple_list_of uses the trick of chaining call operator expressions in order to declare a "list of tuples", e.g:
std::vector<tuple> v = boost::assign::tuple_list_of(1, "foo")(2, "bar")(3, "qqq");
Due to CXXOperatorCallExpr calculating its source range recursively we would get
significant slowdowns with a large number of chained call operator expressions and the
potential for stack overflow.

This was exposed by SingleSource/UnitTests/Vector/constpool.c.
The computed size of a basic block isn't always a multiple of its known
alignment, and that can introduce extra alignment padding after the
block.

Thanks to "Gabor Greif" <ggreif@gmail.com> for reporting this problem.
The configure flag should be --with-default-sysroot as documented, and
not --with-sysroot. The reason we don't want to define --with-sysroot
is that GCC has a configure flag by that name and it has a different
semantics.
