[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.
