1ea503a036 The pleasp.s module is no longer in use.

db69c202a4 Oh well. Decided to throw away the separate implementation for leaa0sp, 
because it's not used too much, may sometimes inlined and can easily be
replaced by another entry in leaaxsp.s

acd1233bf2 Greatly improved multiplication routine. Optimized the generic 16x16 one and 
added special cases for 8x16 and 8x8. The former is directly called by the
compiler as tosmula0 and tosumula0 resp.

cbdcab4fdb Change the sematics of callirq and the existing interruptors: The interrupts 
must now return carry set if the interrupt has been handled, and carry clear
if not. The callirq routine will stop calling handlers with the first handler
that claims to have handled the interrupt. callirq will return the carry flag
to the caller as it came from the last interruptor called.
