library/array.m:
Add uint versions of most of this module's operations.
NEWS.md:
Mention the new operations.
library/edit_distance.m:
Use the new array operations to eliminate some casts.
library/edit_seq.m:
Minor style fix.
tests/hard_coded/array_gen.{m,exp}:
tests/hard_coded/array_test_2.{m,exp}:
Extend the tests of array.m's operations to the corresponding uint
versions. Expect the output for the new versions.
tests/hard_coded/array_resize.m:
tests/hard_coded/array_shrink.m:
Extend the tests of array.m's operations to the corresponding uint
versions, but generate output only if their results differ from the
original int versions. (They don't differ.)
tests/hard_coded/array_primitives.m:
Style fixes.
library/array.m:
Workaround the fact that C#'s 'is' operator has some fairly surprising
behaviour with arrays of integer types.
tests/hard_coded/array_primitives.{m,exp}:
tests/hard_coded/array_shrinks.{m,exp}:
Improve the coverage of these tests.
Add a regression test for the bug fixed in commit 65f683e. There were multiple
places that had the same underlying issue; the new test case covers those as
well.
tests/hard_coded/Mmakefile:
tests/hard_coded/array_primitives.{m,exp}:
Add the new test case.
