select: simplify SEL(SEL(x, C, 0), y, z) --> SEL(x, y, z) and its dual
If the condition of a select is also a select but with constant
operands, some simplification can be done:
* if the second operand is 0, the original condition can be used,
* idem if the first operand is 0s but the operand must be swapped.
