If the first parameter to Fiddle::Function is a closure object (rather
than an interger), `rb_Integer` will cast it to an integer but not
maintain a reference to the closure. Then if the closure gets GC'd, we
have a segv. This commit keeps a reference to the original parameter to
initialize so that the object will not be GC'd.

Previously, the type of these arguments were not checked, leading to
NoMethodErrors in some cases, and TypeErrors in other cases, but not
showing what field was having the problems. This change makes it so
the field with the problem is included in the error message.
For the valid_*? methods, this changes them to return false if one
of the arguments that should be numeric is not.

Previously, julian dates would not round trip through to_time.to_date,
because Time is always considered gregorian. This converts the Date
instance from julian to gregorian before converting to Time, ensuring
that an equal date object will be returned if converting that Time
back to Date.
This does result in julian Date objects showing different day values
if converting to Time.

To perform a regular method call, the VM needs two structs,
`rb_call_info` and `rb_call_cache`. At the moment, we allocate these two
structures in separate buffers. In the worst case, the CPU needs to read
4 cache lines to complete a method call. Putting the two structures
together reduces the maximum number of cache line reads to 2.
Combining the structures also saves 8 bytes per call site as the current
layout uses separate two pointers for the call info and the call cache.
This saves about 2 MiB on Discourse.
This change improves the Optcarrot benchmark at least 3%. For more
details, see attached bugs.ruby-lang.org ticket.
Complications:
- A new instruction attribute `comptime_sp_inc` is introduced to
calculate SP increase at compile time without using call caches. At
compile time, a `TS_CALLDATA` operand points to a call info struct, but
at runtime, the same operand points to a call data struct. Instruction
that explicitly define `sp_inc` also need to define `comptime_sp_inc`.
- MJIT code for copying call cache becomes slightly more complicated.
- This changes the bytecode format, which might break existing tools.
[Misc #16258]
If a fiber is invoked with transfer method (such as "f.transfer"),
then the invoked fiber ("f") is labeled as "transferred" and this
fiber can not be invoked with Fiber#resume. This patch adds
transferred attribute for "Fiber#to_s" (and inspect).
