#16 OnBA: dbcc support

[John Wilund]

OnBoardAsm v2.3 only supports 'dbra' of the very useful
series of 'dbcc' instructions. It would be very nice if
all 'dbcc':s could be used.

asm void workingInlineAsm(void){
beginproc
clr.l d0
move #1024, d0
loop ; this is a label
cmp.l #0, d0
beq quit
dbra d0, loop
quit
endproc
}

All other use of dbcc:s will produce errors!
