* Interpreter: Implement floating point conversions
Implemented the following opcodes for the interpreter:
- `FcvtToUint`
- `FcvtToSint`
- `FcvtToUintSat`
- `FcvtToSintSat`
- `FcvtFromUint`
- `FcvtFromSint`
- `FcvtLowFromSint`
- `FvpromoteLow`
- `Fvdemote`

* Fix `I128` bounds checks for `FcvtTo{U,S}int{_,Sat}`
Copyright (c) 2022 Arm Limited
* Fix broken test
