The main objective here is to make it easy to identify what needs to change
in order to use a different sysent generator than the current Lua-based one,
which may be used to MFC some of the changes that have happened so we can
avoid parallel accidents in stable branches, for instance.

As a secondary objective, it's now feasible to override the generator on a
per-Makefile basis if needed, so that one could refactor their Makefile to
use this while pinning generation to the legacy makesyscalls.sh. I don't
anticipate any consistent need for such a thing, but it's low-effort to
achieve.

Add 8548 CPU definition and attributes

  8548 CPU is GCC's name for the e500v2, so accept this in clang.  The
  e500v2 doesn't support lwsync, so define __NO_LWSYNC__ for this as
  well, as GCC does.

  [PowerPC]: Add powerpcspe target triple subarch component

  Summary:
  This allows the use of '-target powerpcspe-unknown-linux-gnu' or
  'powerpcspe-unknown-freebsd' to be used, instead of '-target

commit 36eedfcb3 from llvm git (by Justin Hibbits):

  [PowerPC] Fix powerpcspe subtarget enablement in llvm backend

  Summary:

  As currently written, -target powerpcspe will enable SPE regardless
  of disabling the feature later on in the command line.  Instead,
  change this to just set a default CPU to 'e500' instead of a generic
  CPU.

  As part of this, add FeatureSPE to the e500 definition.

pc_curthread is set by cpu_switch after it stopped using the old
thread (or boot) stack.  This makes the smp_after_idle_runnable()
function not dependent on the internals of the scheduler operations.
