Revert "Include opt_diagnostic.h for DIAGNOSTIC."

This did not do what I thought it did. opt_diagnostic.h is only for
the unused _DIAGNOSTIC, which seems like an abortive attempt to
incrementally convert DIAGNOSTIC to an opt_*.h option rather than a
command-line option.

Include opt_diagnostic.h for DIAGNOSTIC.

...at least, in header files, which may not have already included
libkern.h.

Round of uvm.h cleanup.

The poorly named uvm.h is generally supposed to be for uvm-internal
users only.

- Narrow it to files that actually need it -- mostly files that need
to query whether curlwp is the pagedaemon, which should maybe be
exposed by an external header.

- Use uvm_extern.h where feasible and uvm_*.h for things not exposed
by it. We should split up uvm_extern.h but this will serve for now
to reduce the uvm.h dependencies.

- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use
UVMHIST(ubchist), since ubchist is declared in uvm.h but the
reference evaporates if UVMHIST is not defined, so we reduce header
file dependencies.

- Make uvm_device.h and uvm_swap.h independently includable while
here.

sljit: avoid compiler warning due to switch fallthru on mips

Unsure why, but this is only a problem when building sljit in
userspace via rump, which we don't do by default on mips,
although it's included in the OCTEON kernel.

Not enough to allow setting MKSLJIT=yes on mips but gets us
closer.
