[new/wip] lang/gcc/11

[Pascal Stumpf]

Here's GCC 11.2.  It's not yet done (most importantly, mips64 and
sparc64 have unresolved issues), but I think the current state should be
imported.

Thanks to bcallah@, there's now experimental support for D.  Due to
issues with emulated TLS, libgphobos as a shared library does not work,
and neither does code using fibers.  Everything else should work.(tm)
GDC may serve as a starting point for porting DMD.
