qualified name does not actually refer into a class/class
template/class template partial specialization. 

Improve printing of nested-name-specifiers to eliminate redudant
qualifiers. Also, make it possible to output a nested-name-specifier
through a DiagnosticBuilder, although there are relatively few places
that will use this leeway.

1. Passing something that isn't a string used to cause:
   "argument to annotate attribute was not a string literal"
  make it say "section attribute" instead.

2. Fix the location of the above message to point to the
   bad argument instead of the section token.

3. Implement rdar://4341926, by diagnosing invalid section
   specifiers in the frontend rather than letting them slip all
   the way to the assembler (a QoI win).

An example of #3 is that we used to produce something like this:

/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Expected comma after segment-name
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Rest of line ignored. 1st junk character valued 46 (.).

Daniel improved clang to use llvm_report_error, so now we got:

$ clang t.c -c
fatal error: error in backend: Global variable 'x' has an invalid section specifier 'sadf': mach-o section specifier
      requires a segment and section separated by a comma.

with no loc info.  Now we get:

$ clang t.c -fsyntax-only
t.c:4:30: error: argument to 'section' attribute is not valid for this target: mach-o section specifier requires a segment
      and section separated by a comma
int x __attribute__((section("sadf")));
                             ^

which is nice :)

Note that I'm guessing that *BSD and Solaris do the same thing as Linux 
here, but it's quite possible I'm wrong; if the following testcase 
gives an error on x86-64 with gcc for any of those operating systems, please
tell me:

#include <stdint.h>

int64_t x; long x;

'make test' passes now.

This unifies all the targets supported by an OS into a template.
It also cleans up the differences between the darwin targets.
Also __LP64__ wasn't needed for *BSD, since x86-64 target defines it anyway.

This is simple enough, but then I thought it would be nice to make PrintingPolicy
get a LangOptions so that various things can key off "bool" and "C++" independently.
This spiraled out of control.  There are many fixme's, but I think things are slightly
better than they were before.

One thing that can be improved: CFG should probably have an ASTContext pointer in it,
which would simplify its clients.

-fstack-protector-all.
