Optimize if/select with one arm an EqZ and another a 0 or a 1 (#3822)
(select
(i32.eqz (X))
(i32.const 0|1)
(Y)
)
=>
(i32.eqz
(select
(X)
(i32.const 1|0)
(Y)
)
)
This is beneficial as the eqz may be folded into something on the outside. I
see this pattern in real-world code, both a GC benchmark (which is why I
noticed it) and it shrinks code size by tiny amounts on the emscripten
benchmark suite as well.
