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.
Fixed a bunch of bugs with return/break/continue in loops.
Fixed support for the DMDFE hidden implicit return value variable. This can be needed for some foreach statements where the loop body is converted to a nested delegate, but also possibly returns from the function.
Added std.math to phobos.
Added AA runtime support code, done ground work for implementing AAs.
Several other bugfixes.
