The recent buserr handler cleanup in the Amiga locore.s made the label
...
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

Reorganize buserr/addrerr stuff, to allow omitting unused code in single-cpu

kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.

New zeropage() implementation based on code contributed by Hiroshi Horitomo
...
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641 . I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes. This
reduces the size and complexity of the function.
On the '020, the simpler code is less than 1% slower. Surprisingly, it
is ~3% faster on the '040.

- GLOBAL()/ASGLOBAL() and LOCAL()/ASLOCAL(), for defining global and
local variables with C and ASM labels.
- BSS()/ASBSS(), for defining items in the BSS segment, with C or
ASM labels.
- PANIC("panic message") - shorthand for calling panic() from assembly code.
- VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries
in the vector table.
Also, change RCSID() to pad out the string to even boundary.
