Subject: re: generalizing the delay rtx function

- Provide a clear definition for the DELAY rtx:
The numeric argument is the number of instruction cycles
after the current one, at which the enclosed set expressions
take effect.
is this possible? eg, (sparc) if i do:
ba foo
ld [%l1 + 4], %o0
vs.
ba foo
tst %o0
the load can take *much* longer than the tst?
other than that, i think this looks fine.
