@afonso360, you've been working on the sign-extension bits this PR relies on, as well as the select lowerings that this affects. What are your thoughts on this PR?

I was wondering if it would be better to pass an ExtendOp to normalize_cmp_value, instead of an IntCC. Most of the callers always want a zero-extend and some of them have to fake a condition code in this PR, so maybe passing the choice of sign-extending or zero-extending directly would be more clear.

I don't know what the best way to do this is. I think I understand this PR though, and if it looks good to @afonso360 then it looks good to me.

@jameysharp It is hard to decide use IntCC or ExtendOp as parameter to normalize_cmp_value too.
Because the function named normalize_cmp_value I thought maybe better pass the IntCC.
Actualy IntCC.Equal and IntCC.NotEqual make no differrence.

@jameysharp Maybe a convert So we can accept IntCC and ExtendOP both.

Like convert Intcc ExtendOp convert_intcc_to_extend_op and normalize_cmp_value accept ExtendOp as parameter.

Like (convert Intcc ExtendOp convert_intcc_to_extend_op) and normalize_cmp_value accept ExtendOp as parameter.
