4f8a2e22c0 fix some cfstring related issues: 
1) -fwritable-string does affect the non-utf16 version of cfstrings
   just not the utf16 ones.
2) utf16 strings should always be marked constant, as the __TEXT segment
   is readonly.
3) The name of the global doesn't matter, remove it from TargetInfo.
4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

This fixes rdar://7115750

a18ed9b113 If a global initializer has a non-trivial constructor or destructor, we never want to defer generation of it, even if it is declared static. 
With this change we're finally able to compile and run the (infamous)

#include <string>
#include <iostream>

int main(int argc, char **argv) {
  std::cout << "Hello, World" << std::endl;
}

$ clang hello.cpp -lstdc++ -o hello
$ ./hello 
Hello, World

9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs(). 
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

ff0553ec61 Fix subtle bug in generating LLVM function declarations for builtin functions. 
The decl wasn't being passed down, which meant that function attributes were not
being set correctly. This is particularly important for ARM, since it wants to
override the calling convention. Instead we would emit the builtin with the
wrong calling convention, and instcombine would come along and merrily shred all
the calls to it. :)

generated for an inline function definition, taking into account C99

34ec2ef159 Improve the AST representation and semantic analysis for extern 
templates. We now distinguish between an explicit instantiation
declaration and an explicit instantiation definition, and know not to
instantiate explicit instantiation declarations. Unfortunately, there
is some remaining confusion w.r.t. instantiation of out-of-line member
function definitions that causes trouble here.

d94105a1c2 Don't generate any code for an explicit call to a trivial destructor. 
Now that parsing, semantic analysis, and (I think) code generation of
pseudo-destructor expressions and explicit destructor calls works,
update the example-dynarray.cpp test to destroy the objects it
allocates and update the test to actually compile + link.
The code seems correct, but the Clang-compiled version dies with a
malloc error. Time to debug!
