Change the interfaces for backend methods that create statements to
always pass in the enclosing Bfunction for the statement. Having the
function available simplifies things if a temporary variable has to be
created during the construction of a statement.
This also includes a change to the Mark_lvalue_varexprs helper
class to handle indirections on the left hand side of assignments
(e.g. "*x.y = ...").
