the memory block as having pointers (for scanning) opposite of what it
should. So pointers would not be seen and freed. Should fix a bunch of
regressions with AAs.
Reimplemented support for nested functions/class using a new approach.
Added error on taking address of intrinsic.
Fixed problems with the ->syntaxCopy of TypeFunction delegate exp.
Removed DtoDType and replaced all uses with ->toBasetype() instead.
Removed unused inplace stuff.
Fixed a bunch of issues in the runtime unittests, not complete yet.
Added mini tests.
