Zoltan Somogyi 1457d825ee Fix more C# test failures.
tests/invalid_nodepend/Mercury.options:
tests/invalid_purity/Mercury.options:
    Let several test cases proceed to the compiler invocation we want to test.

tests/submodules/impl_def_literal.m:
    Comment out the atomic goal in this test case. (See below for the reason.)

tests/valid/big_foreign_type.m:
tests/valid/bug318.m:
tests/valid/flatten_conj_bug.m:
tests/valid/ho_and_type_spec_bug.m:
tests/valid/mert.m:
tests/valid/param_mode_bug.m:
    These test cases were missing C# definitions (and in some cases,
    Java definitions) of types and/or predicates. Add them.

tests/warnings/Mercury.options:
tests/warnings/Mmakefile:
    Update references to a not-long-ago renamed file.

tests/warnings/foreign_singleton.m:
    Add Java and C# definitions of some predicates.

tests/warnings/foreign_singleton.exp:
    Update the line numbers in the expected output for C.

tests/warnings/foreign_singleton.exp[23]:
    Add these expected output files for Java and C#.

compiler/simplify_goal.m:
    Generate an error message if we find an atomic goal
    but we are targeting a language which has no definitions
    for the primitive operations used in the implementation of such goals.
    Until now, for tests/submodules/impl_def_literal.m (which until now
    contained an atomic goal), the compiler would generate code that
    aborted at runtime. We report the problem, which avoids the generation
    of code that would abort.
