afonso360 opened PR #4358 from aarch64-bmask-isle to main:

:wave: This PR Moves bmask and bextend to ISLE for aarch64.

Additionally as in #4331 we also remove the vector versions of bextend from the documentation.

It would also be a good idea to consider if we want to do the same to bmask since we did a similar thing to bint in #4299 and it looks like that the only implementation of vector bmask is on the interpreter.

this could use a little more explanation -- "extend to 64 bits first, then this will be all 0s or all 1s and we can duplicate to both halves of 128 bits" maybe?
