[svn r291] Fixed a bunch of the old Phobos tests to work with Tango. Branch statements now emit a new block after it. Fixed the _adSort runtime function had a bad signature. Added a missing dot prefix on compiler generated string tables for string switch. Fixed, PTRSIZE seems like it was wrong on 64bit, now it definitely gets set properly.
