Refer to BOOT and (uflw) by addr in stable ABI
...
Was previously referred to by name+find, which was wasteful.

z80: optimize chkPS
...
Inline it in next and make chkPS, call a newly reserved label for
it directly, removing a layer of indirection. This frees a spot in
the stable ABI.

VE: add 't'

This is the first commit I do entirely in VE. It's a habit I'm planning

Optimize chkPS
...
Use EXX instead of the stack for HL protection and remove all
spurious uses of chkPS,
I wanted to inline chkPS in next because of its "tight loop" status,
but for reasons I don't understand, doing so breaks Collapse OS.
Later...

Replace INITIAL_SP with PS_ADDR conf
...
Now I struggle to remember why I ever did things they way I did.
There must have been a reason...
