Integrate new PCRE test suites

The relevant testoutputNN files were copied from the PCRE distribution and some corrections were done to run_pcre_tests.erl. Also made test generator be more compiler friendly The re_testoutput1_replacement_test and re_testoutput1_split_test modules that are generated by run_pcre_tests.erl (offline, when a new version of PCRE is integrated in the VM) took forever to compile, as one single huge function contained all the tests. The autogenerated tests are now split into ~50 functions, which reduces compile time to approximately a third. New automatic test suites are also generated from the new testoutputNN files, and checked in.
