New support for inserting ais-annotations.
The ais annotations can be inserted via the new ais variants of
the builtin annotation. They mainly differe in that they have an
address format specifier '%addr' which will be replaced by the
adress in the binary.
The implementation simply prints a label for the builtin call
alongside a the text of the annotation as comment and inserts the
annotation together as acii string in a separate section
'ais_annotations' and replaces the usages of the address format
specifiers by the address of the label of the builtin call.
