Have ASTRecordLayout keep track of the key function, in preparation of fixing a synthetic ctor/dtor bug.

Don't try to generate common globals for C++ files, instead of depending on the FE to set NoCommon, and simplify CodeGenOptions initialization.

trivial constructors/destructors, and makes sure the trivial copy assignment
operator is generated when necessary.

 - Sometimes we have to mangle things we wouldn't normally (e.g., because they appear in a template expression).

 - This also tidies up the predicate to be more obvious what is getting mangled.

The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)

The ssp and sspreq function attributes should only be applied to function definitions, not declarations or calls.

This doesn't have any visible effects at the moment because normally the
implicit cast code forces the type to the expected type.

inlined functions. For example, given

  template<typename T>
  class string {
    unsigned Len;

  public:
    unsigned size() const { return Len; }
  };

  extern template class string<char>;

we now give the instantiation of string<char>::size

permitted by the C++0x standard.

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
