[PATCH 06/72] 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. Signed-off-by:
