 - 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;
    ~ ^

join:
        %5 = phi i1 [%3, %eq], [%4, %ne]
        br i1 %5, label %yes, label %no

=>

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.

Also, rename the h-registers.ll test, now that there are more

nested name specifiers.  Now we emit stuff like:

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

instead of:

t.cpp:8:16: error: invalid token after top level declarator

This is inspired by a really awful error message I got from 
g++ when I misspelt diag::kind as diag::Kind.
