Add the options -polly-codegen-trace-stmts and -polly-codegen-trace-scalars. When enabled, adds a call to the beginning of every generated statement that prints the executed statement instance. With -polly-codegen-trace-scalars, it also prints the value of all scalars that are used in the statement, and PHIs defined in the beginning of the statement.
