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.

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

Add a MangleContext and pass it to all mangle functions. It will be used for keeping state, such as identifiers assigned to anonymous structs as well as scope encoding.

Revert "Switch a few clients over to StringLiteral::getString.", this is breaking some projects, but I don't have a test case yet.

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.

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. :)

and GNU inline/extern inline semantics. This solution is simpler,

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.

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!
