Richard Henderson e99c43735a softfloat: Move the binary point to the msb
Rather than point the binary point at msb-1, put it at the msb.
Use uadd64_overflow to detect when addition overflows instead
of DECOMPOSED_OVERFLOW_BIT.

This reduces the number of special cases within the code, such
as shifting an int64_t either left or right during conversion.
