only this year or last year.

Announce the changes.

Replace references to predicates and functions that this diff deletes
with their suggested replacements.
In several test cases, bring the programming style up to date.
tests/hard_coded/shift_test.{m,exp}:
Most of this test case tested the now-deleted legacy shift operations.
Replace these with tests of their non-legacy versions, including
testing for the expected exceptions.
tests/hard_coded/shift_test.{m,exp}:
Don't pass --no-warn-obsolete when compiling shift_test.m anymore.
Estimated hours taken: 1
Change the bit shift functions to perform checking to avoid
implementation defined behaviour.
library/int.m:
Add checking to `int:<<' and `int:>>'.
Add `int:unchecked_left_shift' and `int:unchecked_right_shift'
which do not perform any checking.
compiler/code_util.m:
Replace `int:<<' and `int:>>' with `int:unchecked_left_shift' and
`int:unchecked_right_shift' in the builtin table.
NEWS:
Mention the changes to int.m.
