Get rid of ALIAS_STR

[Mildred Ki'Lya]

Hi,

In the compiler, there is a lot of ALIAS_STR to transform
ABSTRACT_STRING that have to be compared character by character using
'==' into STRING_CONSTANT where pointer comparison '=' is enough.

Now, ALIAS_STR.get is really too much to write, it's not pretty. In a
word, I want to get rid of it.

My proposition is to add Lisaac numeric externals for the following slots:

  - lower_string_constant :INTEGER <- `33`;
  - upper_string_constant :INTEGER <- `34`;
  - item_string_constant i:INTEGER :STRING_CONSTANT <- `35`;

Converting ABSTRACT_STRING to STRING_CONSTANT could be done using an
auto export in ABSTRACT_STRING to_string_constant. This would compare
the ABSTRACT_STRING with all the STRING_CONSTANT, both those of the
compiler, and those that were converted earlier.
