Removing the indirection helps me with readability, at
least. It doesn't seem like there are many other places
in the Ruby code where macros are used like this.

Casting any arguments of rb_class_ivar_set to st_data_t is wrong
as the function does not take any st_data_t parameters anymore.
There's no functional change, as ID, VALUE, and st_data_t are
all the same type, but this reduces confusion and improves
maintainability for future type changes.

Mainly this is to reduce casting a tiny amount; and
probably nothing depends on the order of globals.
Likely no measurable memory usage improvement as globals
are not common, but maybe some weird code out there benefits.

For the loader (first thread which hits autoload, it is wasteful
to have extra elements on the stack. For the lifetime of the

structs.

Now, rb_check_id() returns 0 if corresponding symbol is
pinned dynamic symbol.
There is remaining intern_cstr_without_pindown(), it can return

it does not have impact for performance.
