Got hi8/lo8 asm instructions working

GNU as does not support the #</#> notation asxxx uses to determine
address LSB and MSB. Instead, two instructions have been created on
GNU as and ld (see my stm8-binutils-gdb fork) for this purpose.

On the other hand, I'm upset to see gen.c does not provide an
assembler-agnostic implementation when SDCCasm.c already provides
tools already meant for this.

OTOH, support for the "-C" has been added for --gas.
