Unary and binary duplicate expression elimination (#3047)
Simplifies patterns in which an expression is applied twice to its operands.
`abs(abs(x))` -> `abs(x)`
`ceil(ceil(x))` -> `ceil(x)`
`floor(floor(x))` -> `floor(x)`
`trunc(trunc(x))` -> `trunc(x)`
`nearest(nearest(x))` -> `nearest(x)`
`eqz(eqz(bool(x)))` -> `bool(x)`
`sext(sext(x))` -> `sext(x)`
`neg(neg(x))` -> `x`
`y - (y - x)` -> `x`
`(x ^ y) ^ y` -> `x`
`(x | y) | y` -> `x | y`
`(x & y) & y` -> `x & y`
`(x % y) % y` -> `x % y`
