    [Liftoff] Implement i32/i64 to f32 conversions · 907c7fad
    Clemens Hammacher authored
    This adds support for f32.convert_{s,u}/i{32,64}.
    On 32-bit platforms, i64 conversions are implemented by a call to a c
    function. Since the signature of this c function is very different to
    the currently used functions in Liftoff (in particular they contain an
    out parameter), this CL requires a major refactoring of how Liftoff
    generates c-calls.
