Both these tests were ultimately fixed by the check for
"isIncompleteType" & neither test case was really reduced to a minimal
form. On doing so it becomes apparent that the problem wasn't specific
to templates at all, so I've moved the test case to a more appropriate
test file and added FileCheck verification to it (to show the forward
declaration of the array element type as well as the array alignment and
size being 0 since it cannot be computed). That's about as far down this
rabbithole as I'm willing to go today, so the rest of the un-FileChecked
tests in test/CodeGenCXX/debug-info.cpp will have to go another day
without actually testing anything other than the fact that they don't
crash.
& improve the actually interesting test case in
test/CodeGenCXX/debug-info-templates.cpp which was my original goal (in
preparation for expanding it/fixing some related bugs in non-type
template parameters)

Summary:
This only supports converting along non-virtual inheritance paths by
changing the field offset or the non-virtual base adjustment.
This implements three kinds of conversions:
- codegen for Value conversions
- Constant emission for APValue
- Constant folding for CastExprs
In almost all constant initialization settings
EmitMemberPointer(APValue) is called, except when the expression
contains a reinterpret cast.
reinterpret casts end up being a big corner case because the null value
changes between different kinds of member pointers.

This was added, untested (though the relevant crash was tested), in
r128725/PR9600. Removing it doesn't cause failures & nothing I can
imagine could cause this check to ever return 'true' (we should never be
dealing with dependent types here). The subsequent change to check
"isIncompleteType" (r128855/PR9608) makes a lot more sense.

EmitCapturedStmt creates a captured struct containing all of the captured
variables, and then emits a call to the outlined function. This is similar in
principle to EmitBlockLiteral.
GenerateCapturedFunction actually produces the outlined function. It is based
on GenerateBlockFunction, but is much simpler. The function type is determined
by the parameters that are in the CapturedDecl.
Some changes have been added to this patch that were reviewed as part of the
serialization patch and moving the parameters to the captured decl.

object x, x's subobjects can be constructed by constexpr constructor even if
they are of non-literal type, and can be read and written even though they're
not members of a constexpr object or temporary.

clang would omit 'C' for 'copy' properties and '&' for 'retain' properties if
the property was also 'readonly'. Fix this, which makes clang match gcc4.2's
behavior.
Fixes PR15928.

After r180934 we may initiate module map parsing for modules not related to the module what we are building,
make sure we ignore the header file info of headers from such modules.

If the LHS of a binary expression is broken, clang-format should also
break after the operator as otherwise:
- The RHS can be easy to miss
- It can look as if clang-format doesn't understand operator precedence
Before:
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
bbbbbbbbbbbbbbbbbb && ccccccccc == ddddddddddd;
After:
bool aaaaaaaaaaaaaaaaaaaaa =
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa != bbbbbbbbbbbbbbbbbb &&
ccccccccc == ddddddddddd;
As an additional note, clang-format would also be ok with the following
formatting, it just has a higher penalty (IMO correctly so).
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
bbbbbbbbbbbbbbbbbb &&
ccccccccc == ddddddddddd;

Summary:
Most of this change is wiring the pragma all the way through from the
lexer, parser, and sema to codegen. I considered adding a Decl AST node
for this, but it seemed too heavyweight.
Mach-O already uses a metadata flag called "Linker Options" to do this
kind of auto-linking. This change follows that pattern.
LLVM knows how to forward the "Linker Options" metadata into the COFF
.drectve section where these flags belong. ELF support is not
implemented, but possible.
This is related to auto-linking, which is http://llvm.org/PR13016.

Before:
aaaaaaaa::
aaaaaaaa::
aaaaaaaa();
After:
aaaaaaaa::
aaaaaaaa::
aaaaaaaa();
The reason for the change is that:
a) we are not sure which is better
b) it is a really rare edge case
c) it simplifies the code
d) it currently causes problems with memoization

Basic support is implemented here - it still doesn't account for
declared-but-not-defined variables or functions. It cannot handle out of
order (declared, 'using', then defined) cases for variables, but can
handle that for functions (& can handle declared, 'using'd, and not
defined at all cases for types).
