Afonso Bordado 7a3df7dcc0 riscv64: Improve ctz/clz/cls codegen (#5854) ...

* cranelift: Add extra runtests for `clz`/`ctz`

* riscv64: Restrict lowering rules for `ctz`/`clz`

* cranelift: Add `u64` isle helpers

* riscv64: Improve `ctz` codegen

* riscv64: Improve `clz` codegen

* riscv64: Improve `cls` codegen

* riscv64: Improve `clz.i128` codegen

Instead of checking if we have 64 zeros in the top half. Check
if it *is* 0, that way we avoid loading the `64` constant.

* riscv64: Improve `ctz.i128` codegen

Instead of checking if we have 64 zeros in the bottom half. Check
if it *is* 0, that way we avoid loading the `64` constant.

* riscv64: Use extended value in `lower_cls`

* riscv64: Use pattern matches on `bseti`
