egraphs: Add some `select` optimizations (bytecodealliance#6843)

* egraphs: Remove extends before selects when possible

* egraphs: Rewrite `select {i,fcmp}` when select arms match cmp result

* egraphs: Simplify double `bmask`

* egraphs: Simplify double `bswap`

* egraphs: Modularize select optimizations

* egraphs: Remove `bmask {i,f}cmp` optimizations

These were unsound since we only represent the results of `{i,f}cmp` as
`-1` for vectors, and not for scalars, scalars get the output of `1`

* egraphs: Optimize `bitrev` in `select` and `bmask`

* egraphs: Optimize `popcnt` in `select` and `bmask`

* egraphs: Optimize double `bitrev`

* egraphs: Add `thruthy` expression matcher

Cleans up the previous logic a bit.

This also adds `rotl`/`rotr` as thruth preserving expressions. As well as
`select` when it's branches match certain constants.

* egraphs: Make `icmp ne x, 0` a thruthy expression

* egraphs: Add `icmp ne x, 0` as an expression that can delete thruthy inputs

* egraphs: Add tests for comutative versions of the `icmp ne` thruthy rules

* egraphs: Restrict `icmp ne` optimization to arms with the

This also cleans up some merge conflicts that happened when rebasing.

* egraphs: Restore some accidentally deleted tests

* egraphs: Use `t` and `f` as names for select arms

* egraphs: Allow `icmp ne` opt to match arms of different types
