library/math.m:
Since code in math.m uses C macros defined in a foreign_decl in float.m,
math.m needs a foreign_import_module for float, but it did not have one.
This caused compilation of math.c to math.o to fail *except* with
intermodule optimization, which gave math.m the required access to
float.m's internals anyway. The reason we didn't notice is that
intermodule optimization is the default.

ssdb/ssdb.m:
As above. This mostly involved two things.
The first was grouping foreign_procs by predicate instead of by language.
In a few cases, this revealed that some predicates *had* no foreign_proc
for a language, while related predicates did have one that just aborted
if called. This diff adds similar aborting foreign_procs to predicate/
language combinations that were missing them, when this seemed obviously
the right thing to do.
The second was moving pragmas about a predicate from the middle of the
block of clauses of that predicate to the start of that block.

Discussion of these changes can be found on the Mercury developers
mailing list archives from June 2018.
COPYING.LIB:
Add a special linking exception to the LGPL.
*:
Update references to COPYING.LIB.
Clean up some minor errors that have accumulated in copyright
messages.
Many predicates that do their jobs via foreign_procs in C have a fallback
Mercury clause for non-C backends, which usually throws an exception.
When compiled in non-C grades, these often get a warning that their
determinism declaration could have been tigther, e.g. erroneous instead of det.
*.m:
Add no_determinism_warnings pragmas before such fallback clauses.
library/dir.m:
As above, but also remove the unnecessary "dir." prefix on many predicate
declarations and clause heads.
NOTE: this change does not affect the io module -- I've left that for a

Allow inlining of Java foreign_procs.
This revealed a problem with directly using the `succeeded' flag directly as
the success indicator in Java foreign_procs. When the code of the foreign_proc
becomes a nested function, and after nested functions are eliminated, there may
not be a variable called `succeeded' in that context; it is moved into
environment struct, and the transformation is not able to update handwritten
code to reflect that. The solution is to declare a local variable for the
foreign_proc, let the handwritten code assign that, then assign its final
value to the `succeeded' flag with an MLDS statement.
We take the opportunity to name the local variable `SUCCESS_INDICATOR', in
line with other backends.
compiler/inlining.m:
Allow inlining of Java foreign_procs.
compiler/ml_foreign_proc_gen.m:

Implement the TypeCtorInfo RTTI so that generic compare
and unify work via rtti_implementation.
However after discussion with zs, this current design of
RTTI has to be adapted to become more erlang specific, due
to the different data representation on the erlang backend.
The current code will serve as a template for this new design
though, which is why it is being checked in.
Add various erlang library implementations which are
needed to run useful programs when testing the erlang backend.

compiler/use_local_vars.m:
Extend this optimization to handle temporaries being both defined in
and used by foreign_proc_code instructions. This should eliminate
unnecessary accesses to the MR_fake_reg array, and thus speed up
programs that use foreign code a lot, including typeclass- and
tabling-intensive programs, since those features are implemented using
inline foreign code. I/O intensive should also benefit, but not much,
since the cost of the I/O itself overwhelms the cost of the
MR_fake_reg accesses.
Group together the LLDS instructions that are handled similarly.
Factor out some common code.

Allow for the fact that foreign_proc_codes can now refer to
temporaries.

Rename the types and function symbols of the recently added
foreign_proc attributes to avoid clashing with the keywords

whether the body of foreign code is allowed to be duplicated.
compiler/table_gen.m:
Include does_not_affect_liveness among the annotations for the
foreign_proc calls generated by this module. Some of these procedures
affect memory beyond their arguments, but that memory is in tables,
not in unlisted registers.
Allow some of the smaller code fragments generated by this module
to be duplicated.
compiler/inlining.m:
Respect the may_not_duplicate foreign_proc attribute.
compiler/pragma_c_gen.m:
Transmit any annotations about liveness from the HLDS to the LLDS,

Bug fix for math library.
library/math.m:
Changed the order of the parameters for the mercury implementation of
math__log_2/2
The old version is incorrect with respect to the library documentation.
'math__log(B, X) = Log' is supposed to return Log as the logarithm to
base B of X. After doing domain checks, this predicate calls
math__log_2(B, X), which is defined correctly for the C and C#
implementations, but had the parameters the wrong way around for the
(default) mercury implementation, so it in fact returned Log as the
logarithm to base X of B (in other words the reciprocal of what was
intended).
