Subject: [PATCH] Add test for postfix if/unless/while/until

The postfix form for if/unless/while/until is detected in IRB Ruby parser
with special token types of Tk{IF,UNLESS,WHILE,UNTIL}_MOD,
but the detection is a new feature in parser.y after parsed
with EXPR_LABEL bit,
it's introduced after the birth of IRB.
So this is an important test to replace Ruby parser of IRB with Ripper.
