* vm.c: fix mark miss for proc given as passed block.

  [Bug #11750]

* vm.c (vm_make_proc_from_block): should return a Proc object
  if block is given. Previous implementation returns
  a Proc object only when corresponding Proc object is not
  available.

* vm.c (vm_make_env_each): ditto.

* test/ruby/test_proc.rb: add a test for this bug.
