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.

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

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. :)

generated for an inline function definition, taking into account C99
and GNU inline/extern inline semantics. This solution is simpler,
cleaner, and fixes PR4536.
