cast: specialize floats to integer conversion
Currently, casts from floats to integers are processed like
integers (or any other type) to integers. This is simple but
rather unconvenient as it correspond to different operations
that obeys to different rules and which later need extra checks.
Change this by directly using specific instructions:
- FCVTU for floats to unsigned integers
- FCVTS for floats to signed integers
