  New Revision: 63484

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=63484

  Log:
    parse.y: use ruby_sized_xfree and SIZED_REALLOC_N
    
    Another part of the plan to reduce dependencies on malloc_usable_size
    which costs us speed: https://bugs.ruby-lang.org/issues/10238
