parse.y: set used flag in gettable

Browse source 
* parse.y (dvar_defined_ref, dvar_defined): rename macros.  only
  gettable uses the former.  assignable should not set LVAR_USED
  flag.

* parse.y (gettable_gen): set used flag on local/dynamic variables
  instead of setting in lexer.  [ruby-core:82368] [Bug #13809]
