Also let clang-format-diff.py detect errors based on clang-format's
return code. Otherwise messages like "Can't find usable .clang-format,
falling back to LLVM style" can make it fail, which might be undesired.

Patch by Alp Toker. Thank you!

The bool conversion operator on InstantiatingTemplate never added value and
only served to obfuscate the template instantiation routines.

This replaces the conversion and its callers with an explicit isInvalid()
function to make it clear what's going on at a glance.

Specifically make ConstructorInitializerAllOnOneLineOrOnePerLine work
nicely with BreakConstructorInitializersBeforeComma.

This fixes llvm.org/PR17395.

llvm-svn: 192168

As described by Richard in https://groups.google.com/a/isocpp.org/d/msg/std-discussion/S1kmj0wF5-g/fb6agEYoL2IJ

we should allow:

template<typename S>
struct A {

template<typename T> static auto default_lambda() {
  return [](const T&) { return 42; };
}

template<class U = decltype(default_lambda<S>())>
  U func(U u = default_lambda<S>()) { return u; }

};

int run2 = A<double>{}.func()(3.14);

int run3 = A<char>{}.func()('a');

This patch allows the code using the same trickery that was used to allow the code in non-member functions at namespace scope.


Please see http://llvm-reviews.chandlerc.com/D1844 for richard's approval.

Summary:
Operator new, new[], delete, and delete[] are all implicitly static when
declared inside a record.  CXXMethodDecl already knows this, but we need
to account for that before we pick the calling convention for the
function type.

Fixes PR17371.

In r186373, we started merging attributes on typedefs, but this causes
us to try to merge attributes even if the previous declaration was not
a typedef.

Only merge the attributes if the previous decl was also a typedef.

An updated version of r191586 with bug fix.

Struct-path aware TBAA generates tags to specify the access path,
while scalar TBAA only generates tags to scalar types.

We should not generate a TBAA tag with null being the first field. When
a TBAA type node is null, the tag should be null too. Make sure we
don't decorate an instruction with a null TBAA tag.

Added a testing case for the bug reported by Richard with -relaxed-aliasing
and -fsanitizer=thread.

This change doesn't go all the way to making fields redeclarable; instead, it
makes them 'mergeable', which means we can find the canonical declaration, but
not much else (and for a declaration that's not from a module, the canonical
declaration is always that declaration).

Summary:
Use the arguments given to the OS at process creation-time instead of
the arguments passed into main() by the C runtime environment.  The ones
that main() received may not be suitable (e.g. not Unicode).

In chicago, Doug had requested that I go ahead and commit the refactor  as a separate change, if all the tests passed.  

Lets hope the buildbots stay quiet.

In functions that only need to use the CGCXXABI member of a CodeGenTypes
class, pass that reference around directly rather than a reference to
a CodeGenTypes class.
