Hi,

This patch merges the D front-end implementation with dmd upstream 5220ad51e.

Backports Ddoc fix that is present in upstream, but did not make its
way into the C++ port of the D front-end implementation.

The old special types for C long, unsigned long, and long double have
also been removed as neither the compiler nor druntime bindings
support handling it anymore.

Commits merged from dmd.
