For something like this:

# 42 "bar.c" 1
# 142 "bar2.c" 1

#warning zappa
# 92 "bar.c" 2
#warning gonzo
# 102 "foo.c" 2
#warning bonkta


we now produce these three warnings:

#1:
In file included from foo.c:3:
In file included from bar.c:42:
bar2.c:143:2: warning: #warning zappa
#warning zappa
 ^

#2:
In file included from foo.c:3:
bar.c:92:2: warning: #warning gonzo
#warning gonzo
 ^

#3:
foo.c:102:2: warning: #warning bonkta
#warning bonkta
 ^

 ^
foo.h:94:2: warning: #warning blarg!

blarg indeed!

with:

#line 92 "foo.h"
#warning blarg!
#warning blarg!

we now emit:

foo.h:92:2: warning: #warning blarg!
#warning blarg!

SourceManager::getPresumedLoc because we now just decompose
the sloc once.

makes it clear to clients that they have to pick an instantiation
or spelling location before calling it and allows optimization based
on that.

infrastructure to construct function type.
 - For consistencty, we should probably always use this to construct
   function types, but these are absolutely necessary to ensure that
   we can emit calls to these functions.

a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:

  - In an unqualified call g(x), even if the name does not refer to
    anything in the current scope, we can still find functions named
    "g" based on ADL. We don't yet have this ability.
  - ADL will need updating for friend functions and templates.

Pointers to functions don't work yet, and pointers to overloaded functions even less. Also, far too much illegal code is accepted.

 - Now only 27/500 failures on ABITest single argument tests; from
   350/500. :)
 - As with return types, a large percentage of these are likely to be
   gcc bugs, not yet reviewed.

Also, fix bug in handling of Ignore ABI type in argument lists.
