@afonso360 Looks like The test failure indicates
x64not implement for small types.

@afonso360 I have rewritten to
ISLE.
fmax_I can't find a suitable name for this.
Maybe you can review code first.

@afonso360 any idea about this failure.
test interpret
test run

Well, looks like we are not returning 0 for all NaN's. When testing this locally I got
run: %b(-NaN:0x7ffffff666666) == 0, actual: -32768so it seems like something is going wrong in the NaN checking.<details>

I haven't looked too close at this, but it looks like we only do the NaN check after the value is clamped, so could that be the reason for the issues?
I also tested building an equivalent test case using LLVM It looks like they do the NaN check on the original input.

Apologies I didn't see this before I ended up making https://github.com/bytecodealliance/wasmtime/pull/7327, but I believe that that PR covers this one so I've annotated that to close this when merged.
