d: Import dmd b8384668f, druntime e6caaab9, phobos 5ab9ad256 (v2.098.0-beta.1)
The D front-end is now itself written in D, in order to build GDC, you
will need a working GDC compiler (GCC version 9.1 or later).
GCC changes:
- Add support for bootstrapping the D front-end.
These add the required components in order to have a D front-end written
in D itself. Because the compiler front-end only depends on the core
runtime modules, only libdruntime is built for the bootstrap stages.
D front-end changes:
- Import dmd v2.098.0-beta.1.
Druntime changes:
- Import druntime v2.098.0-beta.1.
Phobos changes:
- Import phobos v2.098.0-beta.1.
The jump from v2.076.1 to v2.098.0 covers nearly 4 years worth of
development on the D programming language and run-time libraries.

libatomic.
