Subject: * parse.y (do_block): split "do" block and tLBRACE_ARG block.

* parse.y (cmd_brace_block): new tLBRACE_ARG block rule

* parse.y (command): can take optional cmd_brace_block; use %prec
  to resolve shift/reduce conflict. (ruby-bugs-ja PR#372)

* eval.c (ruby_finalize): trace_func should be cleared here (after
  executing exit procs and finalizers).

* eval.c (rb_define_alloc_func): new allocation framework, based
  on Nobu's work [ruby-dev:19116].  "allocate" method is no longer
  used for object allocation.
