 - 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;

kind PCH handles that has an expression as an operand, so most of this
work is in the infrastructure to rebuild expression trees from the
serialized representation. We now store expressions in post-order
(e.g., Reverse Polish Notation), so that we can easily rebuild the
appropriate expression tree.

This allows it to accurately measure tokens, so that we get:

t.cpp:8:13: error: unknown type name 'X'
static foo::X  P;
       ~~~~~^

instead of the woefully inferior:

t.cpp:8:13: error: unknown type name 'X'
static foo::X  P;
       ~~~~ ^

Most of this is just plumbing to push the reference around.
