Arithmetic overflows now return float rather than wrapping around.
* data.c: Include <intprops.h>.
(arith_driver): Use floating point if the accumulator would otherwise
go out of EMACS_INT range.
(arith_driver, Fadd1, Fsub1): Use floating point if the result is
out of Emacs fixnum range.
* bytecode.c (exec_byte_code): Likewise, for Bsub1, Badd1, Bnegate.
