treated as integer, add to table hash of case that way.
based on a patch from Ikuo KOBORI. [ruby-dev:42038]
* insnf.def (opt_case_dispatch): ditto.
* test/ruby/test_case.rb: add tests.

array as argument.
* test/ruby/test_*.rb: moved invariants to left side in
assert_equal, and use assert_nil, assert_raises and so on.

* test/ruby/test_*.rb: split sample/test.rb into 28 test/unit testcases. some
tests could not be translates... search '!!' mark to see it.
* test/csv/test_csv.rb: should require 'csv', not '../lib/csv'. test runner
should set load path correctly.
