Some parts of the infrastructure could do with some TLC.

CI currently uses semaphore CI for native x86_64, and Buildkite 
with a couple
hosted Linux VMs for testing various cross-compilers.  I used to 
have ARM and
ARM64 bare metal servers with Scaleway, but sadly they decided to 
scrap them.

Ideas that could be investigated:

   1. Is Cirrus CI good enough to build gdc?  And if so, look into 
adding
      Windows, MacOSX, and FreeBSD platforms to the pipeline.

   2. Likewise, have a look a Github Actions, they have Windows 
and MacOSX.

   3. Use Docker+QEMU to have containers doing CI for other 
architectures, can
      build images for Alpine and Debian on amd64, arm32v7, 
arm64v8, i386,
      mips64le, ppc64le, and s390x.

   4. I can order VMs with x86_64 FreeBSD and OpenBSD installed 
for CI purposes.
      DragonflyBSD might also be possible as well (I'll have to 
ask for images).

   5. Should builds be packaged up as possible downloads?

There are some compiler/library programming tasks that go with 
it, for each
platform/cpu combination that currently lacks run-time support.

   1. Add relevant target support to GCC.  I have patches, just 
not committed to
      mainline due to lack of testing.

   2. Ensure that druntime builds and is functional on the 
platform.
