Implement i32 - i64 conversion operations #41

Closed matetokodi closed 1 year ago

matetokodi commented 1 year ago

This implements:

I32WrapI64 (i32.wrap_i64)
I64ExtendI32S (i64.extend_i32_s)
I64ExtendI32U (i64.extend_i32_u)

I also implemented unary operations, but @kulcsaradam has also did, and on first look he did it better, so that PR (https://github.com/Samsung/walrus/pull/39) should probably go first.

Now that #39 is in, I have rebased onto the latest jit branch, this should be good to go.
