tests/hard_coded/string_code_point.m:
Avoid an ambiguity due to this module defining its own version of clamp/3.
XXX we should replace the local one with a call to int.clamp/3, but this
module constructs ranges where Max < Min and aborts with the new one.

compiler/pred_table.m:
When typechecking leaves am ambiguity unresolved, a predicate
in this module used to pick one of the candidate matches effectively
at random to "resolve" it.
After the change to enum.m, this led to a compiler abort when compiling
uint.m. The ambiguity was between uint.from_int/2 and the new
enum.from_int/2. The old algorithm picked enum.from_int/2, and tried
to look up its class constraints in the current class context; this failed
with an abort, because the current class context was empty.
Fix this by choosing the match (or *a* match) with the fewest typeclass
constraints to "resolve" any ambiguities.

A test case for the change to pred_table.m.

Mark the X_to_doc function in each of these modules as obsolete,
and make it a forwarding function to the actual implementation
in pretty_printer.m. The intention is that when these forwarding
functions are eventually removed, this will also remove the dependency
of these modules on pretty_printer.m. This should help at least some
of these modules escape the giant SCC in the library's dependency graph.
(It does not make sense that a library module that adds code to increment
an int thereby becomes dependent on pretty_printer.m through int.m.)
library/pretty_printer.m:
Move all the X_to_doc functions from the above modules here.
Fix the one_or_more_to_doc function, which was
- missing the comma between the two arguments of the one_or_more
function symbol, and
- would print "..., ...]" instead of just "...]" at the end of the
tail list when that list exceeded the limits of the specified pp_params.
Rename one of the moved types along with its function symbols,
to reduce ambiguity.
Put arrays before their indexes in the argument lists of some of
the moved functions.
Some of the moved X_to_doc functions for compound types returned
a doc that had an indent wrapper. These indents differed between the
various X_to_doc functions without any visible reason, but they are
also redundant. The callers can trivially add such wrappers if they
want to, but taking them off, if they want them off, is harder.
Eliminate the problem by deleting all such indent wrappers.
Add formatters for the intN, uintN and one_or_more types to the
default formatter map. Their previous absence was an oversight.
Add a function, get_formatter_map_entry_types, that returns the ids
of the types in the formatter_map given to the function. It is intended
for tests/hard_coded/test_pretty_printer_defaults.m, but is exported
for anyone to use.
tests/hard_coded/test_pretty_printer_defaults.{m,exp}:
Use get_formatter_map_entry_types to print the default formatter map
in a format that is much more easily readable.

library/enum.m:
Add the typeclass uenum, which is a version of the existing enum typeclass
that maps items to uints, not ints. It also uses a semidet predicate,
not a semidet function, to get back to the item from the uint.
library/sparse_bitset.m:
library/fat_sparse_bitset.m:
Make these modules operate on uints, which means requiring the items
in the sets to be instances of uenum, not enum.
If a few places, improve loops by doing previously-repeated conversions
of [u]ints into <offset, bit-to-set> pairs just once.
library/counter.m:
Define ucounters, which allocate uints. Improve documentation.
library/digraph.m:
Change digraph_keys from ints to uints, since we put them into
sparse_bitsets.

Make int an instance of the uenum typeclass. This can help users
who currently put ints into sparse_bitsets.

library/term.m:
Make vars instances of uenum as well as enum.

Currently, the hash functions for (some of) the primitive types are defined in
three places:
1. The hash_table module.
2. The version_hash_table module (duplicates of the above).
3. Some (but not all) of the library modules for the primitive types.
This change makes the library module for a primitive type provide the hash
function for that type and deprecates the versions in the hash table modules.
Additionally, deprecate the "generic" has functions in the hash table modules.

tests/hard_coded/test_pretty_printer_defaults.exp:
Conform to the above change to the pretty_printer module.
Add a new builtin type: uint, which is an unsigned word sized integer type.
Support for this new type will need be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognize 'uint' as a builtin type.
- Extends the set of builtin operations to include relational and (some)
arithmetic operations on uints.
- Extends all of the code generators to handle the above. There are some
limitations currently marked by 'XXX UINT'. These will be lifted once
the compiler recognised uint and additional library support becomes
available.
- Extends the runtime to support uints.
compiler/prog_type.m:

Add a new alternative to the cons_id/0 type corresponding to the uint type
-- for bootstrapping purposes its argument is currently an int.
compiler/builtin_ops.m:
Add builtin relational and arithmetic operations on uints. Note that the
existing 'unsigned_le' operation is actually intended for use with signed
values. Rather than attempt to modify its meaning, I have just added new
operations specific to the uint type.
