bare_instructions.rb: sp_inc is signed

Browse source 
* tool/ruby_vm/models/bare_instructions.rb (predefine_attributes):
  `sp_inc` attribute which may return negative values must be
  signed `rb_snum_t`, to be signed-expanded at type promotion.

* vm_insnhelper.h (ADJ_SP): removed the workaround for platforms
  where rb_num_t is wider than int.
