[PATCH] D, Darwin: Restore bootstrap.

[Iain Sandoe]

Tested on x86_64, i686 darwin17 and aarch64 darwin21,
OK for trunk, or alternate solution?
thanks,
Iain

Recent merges from libphobos have broken bootstrap on many/most Darwin
version (those with 32bit multilibs, 32bit hosts, aarch64 and powerpc).

This is because the thread data are not imported into osthread.d.

Fixed thus:

libphobos/ChangeLog:

        * libdruntime/core/thread/osthread.d: Import thread data for
        i686, aarch64, powerpc and powerpc64.
