- Don't emit anything when we encounter a call to a conversion operator.
"bar(a & b)" instead of "bar(a & b.operator int())"
This preserves the semantics and is still idempotent if we print the AST multiple times.
- Properly print declarations of conversion operators.
"explicit operator bool();" instead of "bool operator _Bool();"

A return type is the declared or deduced part of the function type specified in
the declaration.
A result type is the (potentially adjusted) type of the value of an expression
that calls the function.
Rule of thumb:
* Declarations have return types and parameters.
* Expressions have result types and arguments.

This has the dual effect of (1) enabling more dead-stripping in release builds
and (2) ensuring that debug helper functions aren't stripped away in debug
builds, as they're intended to be called from the debugger.
Note that the attribute is applied to definitions rather than declarations in
headers going forward because it's now conditional on NDEBUG:
/// \brief Mark debug helper function definitions like dump() that should not be
/// stripped from debug builds.
Requires corresponding macro added in LLVM r198456.

__builtin_va_list and friends have been showing up where they shouldn't for way
to long, making unwanted appearences in -ast-print, tooling and source level
visitors and even the hello world tutorial on the clang website.
This commit factors down the implicit typedef and record creation facilities to
ensure they're marked implicit.
Also fixes a unit test that was testing incorrect behaviour, and removes old
hacks in the DeclPrinter that tried to skip implicit declarations manually.

Summary:
In general, this type node can be used to represent any type adjustment
that occurs implicitly without losing type sugar. The immediate use of
this is to adjust the calling conventions of member function pointer
types without breaking template instantiation.
Fixes PR17996.

No functionality change.
In Sema helper functions:
* renamed isTypeName as HasTypenameKeyword
In UsingDecl:
* renamed get/setUsingLocation to get/setUsingLoc
* renamed is/setTypeName as has/setTypename

Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in
CXXCtorInitializers and in InitListExprs to represent a default initializer.
There's an additional complication here: because the default initializer can
refer to the initialized object via its 'this' pointer, we need to make sure
that 'this' points to the right thing within the evaluation.

http://lab.llvm.org:8011/builders/clang-x86_64-darwin10-gdb went back green
before it processed the reverted 178663, so it could not have been the culprit.
Revert "Revert 178663."
This reverts commit 4f8a3eb2ce5d4ba422483439e20c8cbb4d953a41.

For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.
This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.

Introduce a new AST Decl node "EmptyDecl" to model empty-declaration. Have attributes from attribute-declaration appertain
to the EmptyDecl node by creating the AST representations of these attributes and attach them to the EmptyDecl node so these
attributes can be sema checked just as attributes attached to "normal" declarations.

This is an improvement of r173630, that handles the following case:
struct VirualDestrClass
{
VirualDestrClass(int arg);
virtual ~VirualDestrClass();
};
struct ConstrWithCleanupsClass
{
ConstrWithCleanupsClass(const VirualDestrClass& cplx = VirualDestrClass(42));
};
ConstrWithCleanupsClass cwcNoArg;
That was printed as:
ConstrWithCleanupsClass cwcNoArg();

-ast-print prints all declarations found in
all-std-headers.cpp.

fix any bad objectiveC syntax coming out of
DeclPrinter. This is on going. Also, introduce a new
PrintPolicy and use it as needed when declaration tag
is to be produced via DeclPrinter.

use clang's formatter. Currently, formatter is used
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.
