to use them instead of SourceRange.  CharSourceRange is just a SourceRange
plus a bool that indicates whether the range has the end character resolved
or whether the end location is the start of the end token.  While most of
the compiler wants to think of ranges that have ends that are the start of
the end token, the printf diagnostic stuff wants to highlight ranges within
tokens.

This is transparent to the diagnostic stuff.  To start taking advantage of
the new capabilities, you can do something like this:
  Diag(..) << CharSourceRange::getCharRange(Begin,End)

the x86-64 __va_list_tag with this attribute.  The attribute causes the
affected type to behave like a fundamental type when considered by ADL.

(x86-64 is the only target we currently provide with a struct-based
__builtin_va_list)

Fixes PR6762.

to be algorithmically faster and avoid an std::map.  This routine
basically boils down to finding the nearest common ancestor in a

use it!

along.

print the diagnostic category number in the [] at the end
of the line.  For example:

$ cat t.c 
#include <stdio.h>
void foo() {
 printf("%s", 4);
}
$  clang t.c -fsyntax-only -fdiagnostics-print-source-range-info
t.c:3:11:{3:10-3:12}{3:15-3:16}: warning: conversion specifies type 'char *' but the argument has type 'int' [-Wformat,1]
  printf("%s", 4);
          ~^   ~
1 warning generated.

Clients that want category information can now pick the number 
out of the output, rdar://7928231.

diagnostics together (e.g. "Logic Warning", 
"Format String Warning", etc) like the static analyzer does.

   on {armv6, armv7} x {-mno-thumb, -mthumb}, and the first 10k tests for armv7
   -mthumb, for both function return types and single argument calls. These all
   pass now (they failed horribly before without --no-bitfield).
