testing various combinations of displaying variales of basic types. The generic_type_tester() works by first capturing the golden output produced by the printf stmts of ./a.out, creating a list of (var, value) pairs, and then running the a.out to a stop point, and comparing the 'frame variable var' output against the list of (var, value) pairs. Modified int_type() and added long_type() to use generic_type_tester(). Also modified TestBase.expect() such that substring matching also return ok if the substring starts at the 0-th position. llvm-svn: 114708
