softfloat: Make the int-to-float functions take exact-width types
Currently the int-to-float functions take types which are specified as "at least X bits wide", rather than "exactly X bits wide". This is confusing and unhelpful since it means that the callers have to include an explicit cast to [u]intXX_t to ensure the correct behaviour. Fix them all to take the exactly-X-bits-wide types instead. Note that this doesn't change behaviour at all since at the moment we happen to define the 'int32' and 'uint32' types as exactly 32 bits wide, and the 'int64' and 'uint64' types as exactly 64 bits wide.
