with LLVM 13.

Add option to build loongson kernels using clang.

The compiler -pg option implies -fno-ret-protector, as we want to disable
retguard and similar when profiling. However, that missed all the .S files,
as ${PROF} wasn't added when ${NORMAL_S} was converted from direct invocation
of ${AS} to instead use ${CC}. Similarly, mcount.o still had retguards
as it cannot be built with -pg. So: pass ${PROF} when compiling .S files,
and compile "no profiling" files with -fno-ret-protector on archs with
retguard.

Further improve the filesystem stability of kernel installation by KARL.
Use install -F to instead of cp, for fsync(2). Coupled with the new
sync(8) in the reorder_kernel script, the window for a incomplete /bsd
file on-disk due to a crash has now shrunk substantially.

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

Since rev 1.502 of rc(8) it creates a /bsd.booted hard link. At the
end of rc we call reorder_kernel which creates a /obsd hard link to
the same kernel.
In the past obsd was only created when doing a manual make install in
the kernel sources.
There is no need for two backup hard links during boot, rearange the
kernel Makefiles to restore previous behaviour and thus stopping
reorder_kernel from scribbling over /obsd.

Makes muscle memory of some kernel developers work again: /obsd can
serve as a known good kernel; and there was much rejoycing...

Discussed at length with benno, rpe, phessler and tb at

When option DDB_STRUCTINFO was removed from the kernel, too much from
the kernel makefiles was removed which lead to C files not being re-

places and generally a broken system.
