Antonio Maiorano 17e83de54f Fix UB when parsing HexFloat with large exponents 
During HexFloat parsing, if exponent was too large, we would overflow
the signed integer being used to store its value. We now use an uint32_t
to avoid UB, then convert to int32_t when it's safe to do so.

Also error out if the input exponent is > INT_MAX - 127, which ensures
we will not wrap around and produce an invalid result when adding the
exponent bias of 127.
