To be precise C90 says "A bit-field may have type int, unsigned
int, or signed int". It is clear that char or enum are NG.

* time.c (wadd): use internal addv() function to calculate internal value in
Time object. On 64-bit machine, Time object might have Fixnum object
internally by default and addv() can calculate Fixnum objects directly.
* time.c (wsub): use internal subv() function due the same reason in above.
Time#+ & Time#- will be faster around 15%.

* time.c (wcmp): use internal cmp() function for comparing internal Fixnum value
in Time objects. On 64-bit machine, Time object might have Fixnum object
internally by default and cmp() can compare the Fixnum objects directly.
Time#<=> will be faster around 60% on 64-bit machine.
* time.c (cmp): add optimized path for comparing internal Bignum value by using
rb_big_cmp() API. On 32-bit machine, Time object might have Bignum object
internally by default.
Time#<=> will be faster around 50% on 32-bit machine.

maybe checking them in wdivmod0() is better manner, but I guess that
passing real dummy pointers may be faster than checking and branching
in wdivmod0().

calls id_quo whose return value is array.

calls id_quo whose return value is array.
