Surpress ImplicitCastExprs for compound assignment expressions. For compound assignments,
it is o.k. for the LHS and RHS to have different types. Converting the type can cause
errors like the one Chris noticed (below).

This change required a fair number of diffs (since there is a lot of shared code

Ted Kremenek [Fri, 24 Aug 2007 18:13:47 +0000 (18:13 +0000)]
Began implementing "child iterator" interface for Stmts and Exprs.  Each
subclass of Stmt will implement child_begin() and child_end(), which will
be used to iterate over all the children (subexpressions/substatements) of
a Stmt object.  This will provide for easy traversal over the AST, which
is useful for a variety of purposes.

None of the interfaces to subclasses of Stmt will be changed (other than
adding the child_begin and child_end methods).

The only caveat is that the implementation of subclasses of Stmt will require
colocating all substatements (subexpressions) in an array.  This is because
we define child_iterator as Stmt**.  All accessor methods to subexpressions
will need to be altered to reflect this new implementation.

This patch includes the typedefs for child_iterator, as well the implementation
for child_begin/child_end for the primary expressions and some postfix
expressions.
