Summary: Please document peephole optimizer syntax

Initial Comment:
Please document the syntax of the peephole optimizer,
so  people can write rules for it without digging
through sdcc source code.

It seems most rules are straightforward - replace this
sequence ba that sequence, but I wonder if more
complicated things are possible , like replace this
sequence containing a jump to label L with that
sequence if there's code C at label L and so on.

Philipp
