variables. For example, with code like this:

  for (i=0;i<n;++i)
    if (i<n)
      x[i] = 0;

IndVarSimplify will now recognize that i is always less than n inside
the loop, and eliminate the if.

Fix CFG bug where bases of member expressions were not always evaluated in a lvalue context.  Fixes <rdar://problem/7813989>.

Fix bug in AddStmtChoice:asLValue() where 'AsLValueNotAlwaysAdd' would not be treated as indicating an lvalue.

LookupInObjCMethod.  Doing so allows all sorts of invalid code
to slip through to codegen.  This patch does not change the 
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.

There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.

typo correction.  However, now that the code has been factored out
of LookupMemberExpr, it can recurse to itself instead of to 
LookupMemberExpr!  Remove grossness.

pointer to an objc interface out to a method in SemaExprObjC.
This is *much* uglier than it should be due to grossness in
LookupMemberExpr :(
