Use the type information from the TemplateParameterList instead

When support was added for declaration arguments, the case of variadic
declaration arguments was not supported. This patch fixes that problem by
not crashing when certain ValueDecl's are null.

Value depenedent expressions for default arguments cannot be evaluated.
Instead, use the desugared template type to get an argument expression that
can be used. This is needed for both integer and declaration arguements.
Also, move this common code into a separate function.

Symbol table function names should support lookups like symbols with debug info.
To fix this I:
- Gutted the way FindFunctions is used, there used to be way too much smarts only in the DWARF plug-in
- Made it more efficient by chopping the name up once and using simpler queries so that SymbolFile and Symtab plug-ins don't need to do as much
- Filter the results at a higher level
- Make the lldb_private::Symtab able to chop up C++ mangled names and make as much sense out of them as possible and also be able to search by basename, fullname, method name, and selector name.

Doxygen treats "@command" the same as "\command" in a doc comment, so
whenever we talk about Objective-C things like "@interface" we have to

- Find the correct region to represent the first array element when
constructing a CXXConstructorCall.
- If the array is trivial, model the copy with a primitive load/store.
- Don't warn about the "uninitialized" subscript in the AST -- we don't use
the helper variable that Sema provides.

Reimplemented the NSDictionary synthetic children provider for added performance.
Instead of generating pairs by running an expression, we now create a pair type using clang-level APIs and fill in a buffer with the pointers to key and value
This strategy takes the time required to dump a 10k items __NSDictionaryM from ~45s to <4s

a normal cleanup when entering a @try or @synchronized to
ensure that we clean that up if an exception is triggered.
Apparently GCC did this, so it's hard to argue that we shouldn't
do at least as much.

Fixing a bug where LLDB was not handling correctly CFStrings that have an explicit length but no NULL terminator
The data formatter was showing garbled data as part of the summary
The fix is to explicitly figure out the explicit length if we need to (bitfields tell us when that is the case) and use that as a size delimiter

implementation of std::is_polymorphic does this:
template <class _Tp> struct __is_polymorphic1 : public _Tp {};
... and that g++ rejects this if _Tp has an inaccessible virtual destructor
(because __is_polymorphic1<_Tp> would have a deleted virtual destructor
overriding _Tp's non-deleted destructor). Clang was failing to reject this;
I've fixed that in r178563, but that causes libc++'s corresponding test
case to fail with both clang and gcc when using the fallback
implementation. The fallback code also incorrectly rejects final types.
The attached patch fixes the fallback implementation of is_polymorphic; we
now use dynamic_cast's detection of polymorphic class types rather than
trying to determine if adding a virtual function makes the type larger:
enable_if<sizeof((_Tp*)dynamic_cast<const volatile
void*>(declval<_Tp*>())) != 0, ...>
Two things of note here:
* the (_Tp*) cast is necessary to work around bugs in Clang and g++ where
we otherwise don't instantiate the dynamic_cast (filed as PR15656)
* the 'const volatile' is here to treat is_polymorphic<cv T> as true for a
polymorphic class type T -- my reading of the standard suggests this is
incorrect, but it matches our builtin __is_polymorphic and gcc

For variable declarations initialized with new expressions, use 'auto' for the
type specifier.
The 'auto' replacement happens only when the type of the VarDecl exactly
matches the type of the initializer and the VarDecl is *not* CV-qualified. The
only case that is currently handled is if the pointer type of the VarDecl is
itself CV qualified.
Some improvements need to be made to Clang's TypeLoc information in order for
other CV qualifier cases to be successfully handled. See the new test suite
new_cv_failing.cpp for examples of usages that could be handled with such an
improvement.
Function pointers are, for now, not transformed until the identifier info can
be extracted.

This patch only adds support for parsing these identifiers in the
X86AsmParser. The front-end interface isn't capable of looking up
these identifiers at this point in time. The end result is the
compiler now errors during object file emission, rather than at
parse time. Test case coming shortly.

Add utilities to create struct nodes in TBAA type DAG and to create path-aware
tags. The format of struct nodes in TBAA type DAG: a unique name, a list of
fields with field offsets and field types. The format of path-aware tags:
a base type in TBAA type DAG, an access type and an offset relative to the base
type.

When doing a partword atomic operation, a lwarx was being paired with
a stdcx. instead of a stwcx. when compiling for a 64-bit target. The
target has nothing to do with it in this case; we always need a stwcx.
Thanks to Kai Nacke for reporting the problem.
