	src/sys/arch/sun3/sun3x: locore.s

Log Message:
Oops missed sun3x in previous changes:

Now that all of the m68k copies of the "rei" function are functionally
equivalent, pick the one that uses the fewest cycles in the "no AST
pending" case and re-factor it into trap_subr.s.

Re-factor badtrap into the shared trap_subr.s.  This time we pick the
sun2/sun3 implementation of this trap stub because it provides more
context to the stray trap reporting routine (adjust the N copies of
straytrap() to compensate as needed, sigh).

Re-factor trap0 (system calls) into trap_subr.s.  Here we pick the flavor
that has the in-line astpending check bcause it's a few cycles faster in
the (common) case where no AST is pending at the end of a system call.

Re-factor trap12 ("cachectl") into trap_subr.s.  Already identical everywhere
except for 68010, where it's a no-op.
