1. YJIT: Fix incomplete invalidation from opt_setinlinecache …

   As part of YJIT's strategy for promoting Ruby constant expressions into
   constants in the output native code, the interpreter calls
   rb_yjit_constant_ic_update() from opt_setinlinecache.
   
   The block invalidation loop indirectly calls rb_darray_remove_unordered(),
   which does a shuffle remove. Because of this, looping with an
   incrementing counter like done previously can miss some elements in the
   array. Repeatedly invalidate the first element instead.
   
   The bug this commit resolves does not seem to cause crashes or divergent
   behaviors.
