Leonardo de Moura 3e1fd06903 refactor(kernel/expr): remove 'null' expression, and operator bool for expression ... After this commit, a value of type 'expr' cannot be a reference to nullptr. This commit also fixes several bugs due to the use of 'null' expressions. TODO: do the same for kernel objects, sexprs, etc. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>		2013-12-07 23:21:10 -08:00
