we model that as

 - This was particularly bad since I fixed one instance of this name
   and not another, meaning we got an LLVM module with the same
   effective name in two different globals!

caused by: <rdar://problem/6252084> [sema] jumps into Obj-C exception blocks should be disallowed.

Sema::RecursiveCalcLabelScopes() and Sema::RecursiveCalcJumpScopes() need to pop the ScopeStack within the statement iteration loop (was outside the loop).

Eli, please review (thanks).

with other diagnostic mapping.  In the new scheme, -Wfoo or -Wno-foo or 
-Werror=foo all override the -pedantic options, and __extension__ 
robustly silences all extension diagnostics in their scope.

An added bonus of this change is that MAP_DEFAULT goes away, meaning that
per-diagnostic mapping information can now be stored in 2 bits, doubling
the density of the Diagnostic::DiagMapping array.  This also 
substantially simplifies Diagnostic::getDiagnosticLevel.

OTOH, this temporarily introduces some "macro intensive" code in 
Diagnostic.cpp.  This will be addressed in a later patch.

 - Set alignment on property lists.
 - 32-bit:
   o Set section on property lists.
   o Fix section name for category class methods.
   o Fix symbol name for property lists.
   o Fix section name for class method.
   o Set alignment and section on class extension structure.
   o Set alignment on a number of things: instance variables, methods,
   method descriptions, the symbols structure.
 - 64-bit:
   o Fix section flags for protocol list.

I doubt most of these were problems in practice, but it is nice to
match llvm-gcc.

 - Strip off extra parens when looking for casts.
 - Change the location info to point at the cast (instead of the
   assignment).

For example, on
  
  int *b;
  #define a ((void*) b)
  void f0() {
    a = 10;
  }
  
we now emit:
  
  /tmp/t.c:4:3: error: assignment to cast is illegal, lvalue casts are not supported
    a = 10;
    ^ ~
  /tmp/t.c:2:12: note: instantiated from:
  #define a ((void*) b)
            ~^~~~~~~~~~
  
instead of:
  
  /tmp/t.c:4:5: error: expression is not assignable
    a = 10;
    ~ ^
