-F Mnemonic: Failure. Used for plugins which print "Failure" to
indicate error. Run phc with the plugin to determine failure.
-Z Require script to return zero when run through interpreter
Sample commands:
reduce -v test/subjects/codegen/0001.php
reduce "-c--run=plugins/tools/debug_zval.la -dump-xml=plugins/tools/debug_zval.la" test/subjects/codegen/0001.php
reduce -v 0001.uhir.php
reduce -F plugins/tests/limit_assignments.la test/subjects/codegen/bench_simple.php
