Fix types of SIMD or, xor, and

Browse Source 
The operands of these bitwise instructions could have different types and still be valid Wasm (i.e. `v128`). Because of this, we must tell Cranelift to cast both operands to the same type--the default type, in this case. This undoes the work merged in https://github.com/bytecodealliance/cranelift/pull/1233.
