Mark iseq structs with rb_gc_mark_movable
Using rb_gc_mark_movable and a reference update function, we can make
instruction sequences movable in memory, and avoid pinning compiled iseqs.
```
require "objspace"
iseqs = []
GC.disable
50_000.times do
iseqs << RubyVM::InstructionSequence.compile("")
end
GC.enable
GC.compact
p ObjectSpace.dump_all(output: :string).lines.grep(/"pinned":true/).count
```
