Thereby, the macro is consistently formatted (including the trailing
escaped newlines) even if clang-format is invoked only on single lines
of the macro.

Summary:
Adds actual config file reading to the clang-format utility.
Configuration file name is .clang-format. It is looked up for each input file
in its parent directories starting from immediate one. First found .clang-format
file is used. When using standard input, .clang-format is searched starting from
the current directory.
Added -dump-config option to easily create configuration files.

MSVC provides __wchar_t. This is the same as the built-in wchar_t type
from C++, but it is also available with -fno-wchar and in C.

The commit changes ASTContext to have two different types for this:

  - WCharTy is the built-in type used for wchar_t in C++ and __wchar_t.

  - WideCharTy is the type of a wide character literal. In C++ this is
    the same as WCharTy, and in C  it is an integer type compatible with
    the type in <stddef.h>.

This fixes PR15815.

Before, the actual operator of an overloaded operator declaration was
handled as a binary operator an thus, clang-format could not find valid
formattings for many examples, e.g.:

template <typename AAAAAAA, typename BBBBBBB>
AAAAAAA operator/(const AAAAAAA &a, BBBBBBB &b);

substitute 'void' into the return type rather than replacing it with 'void', so
that we maintain the 'auto' type sugar.

for C++ constructors.

If the DIType for a class was generated by
CGDebugInfo::createContextChain(), the cache contains only a
limited DIType wihtout any declarations. Since EmitFunctionStart()
needs to find the canonical declaration for each method, we
construct the complete type before emitting any method.

This fixes several (7 out of 16) cases of PR14492 in the GDB 7.5 test
suite. It seems GDB was bailing out whenever it had even the slightest
problem with the template argument list (& I assume it didn't like
seeing template value parameters that were just simple names - perhaps
assuming that lone names must be types, not values)

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)

Patch by Robert Wilhelm.

llvm-svn: 181544

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.

The return type of the destructor may vary between platforms, so stop
inadvertently testing it.

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.
