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().

* time.c (wmul): use mul which has Fixnum optimization.

divmodv has Fixnum optimization.
* time.c (wdiv): use wdivmod0 and div to avoid the use of divmodv which
calls id_quo whose return value is array.
* time.c (wmod): use wdivmod0 and mod to avoid the use of divmodv which
calls id_quo whose return value is array.

expected compiler to handle well.

Such case can be optimized out because quo()'s argument is constant.

This also recovers some performance on other generic ivar objects,

test/ruby/test_float.rb (test_sleep_with_Float) causes tv_nsec
to hit 1000000000 exactly. This bug is currently hidden from
our test by the platform-dependent native_cond_timeout
functions, but a future native_cond_timedwait implementation may
prefer relative timeouts to match ConditionVariable#wait
semantics more closely.

We need to prevent vtm.zone from pointing to a GC-ed string buffer.
The rb_copy_generic_ivar call misses it because get_attr deleted it.
