redundant #includes.  Patch by Anders Johnsen!

.def file for each library.  This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

 - Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

think it is really right. :)  This fixes PR2284.

related to pp-expressions.  Doing so is pretty simple and this
patch implements it, yielding nice diagnostics like:

t.c:2:7: error: division by zero in preprocessor expression
#if 1 / (0 + 0)
    ~ ^ ~~~~~~~
t.c:5:14: error: expected ')' in preprocessor expression
#if (412 + 42
     ~~~~~~~~^
t.c:5:5: error: to match this '('
#if (412 + 42
    ^
t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574
#if (-42 + 0U) / -2
     ~~~ ^ ~~
t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614
#if (-42 + 0U) / -2
    ~~~~~~~~~~ ^ ~~

a) correct rejection of ',' in pp expressions.
b) the precedence of ',' was wrong w.r.t. ?:.

Thanks again to Neil for finding these and providing testcases.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

theoretically useful, but not useful in practice.  It adds a bunch of 
complexity, and not much value.  It's best to nuke it.  One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay).  Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.

Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed.  Please poke at it when you have
time.

discussion of this change.

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

Now instead of IdentifierInfo knowing anything about MacroInfo,
only the preprocessor knows.  This makes MacroInfo truly private
to the Lex library (and its direct clients) instead of being 
accessed in the Basic library.
