over is the subexpression of a sizeof(expression). Different clients
will wish to handle iteration over such subexpressions differently, and can
now easily query if they are iterating over such statements using the
StmtIterator's inSizeOfExpr().

declared in a sizeof. For example:
sizeof(int[foo()]);
the expression "foo()" is an expression that is executed during the evaluation
of sizeof.

of VariableArrayTypes that appear in TypedefDecls.
for example:
typedef int T[x][x];
the StmtIterator will iterate over "x" and "x" as subexpressions of
the DeclStmt for T.

where the decl would always be non-NULL. Moved the check to after the
block to properly tidy up the iterator's state.

of VariableTypeArray types that appear in DeclStmts.
Removed operator-- from StmtIterator. operator-- added undesired
complexity, and we have no consumers of it.

slightly more succinct.
Introduced VariableArrayType* within StmtIteratorBase to (soon)
support iteration over the size expressions of variable length arrays.

visits its decls, rather than just creating an "end()" iterator.
Fixed child_end() for statements and expressions to use
child_iterator() to create the end() iterator, rather than just
returning NULL.
Fixed bug in StmtIterator where we did not correctly detect if we had
marched off the end of the ScopedDecls.

and StmtIteratorImpl (templated), which StmtIterator and
ConstStmtIterator now succintly subclass.
Implemented iteration over the initializers in DeclStmts. This is not
thoroughly tested, so there may be bugs.

that will (soon) allow iteration over the initializers in
declarations. This new iterator mechanism is implemented by the
classes StmtIterator and ConstStmtIterator.
Patched a few files to use "operator++" instead of "operator+" on
child_iterators.
Friendship added in VarDecl to StmtIterator to allow returning a
reference to the initializer within the VarDecl. We may not wish this
as a permanent solution.
