canon: put PSEUDO_REGs in canonical order too
Currently, only binops containing PSEUDO_VAL, SYM or ARG were
put in canonical order. This means that binops containing only
PSEUDO_REGs are not ordered. This is not directly
a problem for CSE because commutativity is taken in account but:
* more combination need to be checked during simplification
* 'anti-commutative' operations like (a > b) & (b < a) are not
recognized as such.
So, take PSEUDO_REGs in account when checking if operands
are in canonical order.
