When a use-associated procedure was included in a generic, we weren't
correctly recording that fact. The ultimate symbol was added rather than
the local symbol.
Also, improve the message emitted for the specific procedure by
mentioning the module it came from.
This fixes one of the problems in https://bugs.llvm.org/show_bug.cgi?id=48648.

Some operators have more than one name, e.g. operator(==), operator(.eq).
That was working correctly in generic definitions but they can also
appear in other contexts: USE statements and access statements, for
example.
This changes FindInScope to always look for each of the names for
a symbol. So an operator may be use-associated under one name but
declared private under another name and it will be the same symbol.
This replaces GenericSpecInfo::FindInScope which was only usable in
some cases.
Add a version of FindInScope() that looks in the current scope to
simplify many of the calls.

When the same generic name is use-associated from two modules, the
generics are merged into a single one in the current scope. This change
fixes some bugs in that process.
When a generic is merged, it can have two specific procedures with the
same name as the generic (c.f. module m7c in modfile07.f90). We were
disallowing that by checking for duplicate names in the generic rather
than duplicate symbols. Changing `namesSeen` to `symbolsSeen` in
`ResolveSpecificsInGeneric` fixes that.
We weren't including each USE of those generics in the .mod file so in
some cases they were incorrect. Extend GenericDetails to specify all
use-associated symbols that are merged into the generic. This is used to
write out .mod files correctly.
The distinguishability check for specific procedures of a generic
sometimes have to refer to procedures from a use-associated generic in
error messages. In that case we don't have the source location of the
procedure so adapt the message to say where is was use-associated from.
This requires passing the scope through the checks to make that
determination.

There were several different ways of handling the option to f18 to
find predefined modules:
- test_errors.sh was created by cmake substituting
FLANG_INTRINSIC_MODULES_DIR into test_errors.sh.in
- some tests used the flang script which has the option built it
- some tests used %f18_with_includes which was replaced by the path
to f18 plus the -I option
- some included -I../../include/flang in their run command
To make this more consistent, change %f18 to include the
-intrinsic-module-directory option and use it everywhere, including
to replace %flang and %f18_with_includes. This requires changing all
of the invocations of the test scripts to put %f18 at the end so that
it can expand to more than one argument.
This eliminates the need to generate test_errors.sh which means we
don't need flang/test/Semantics/CMakeLists.txt or the %B substitution.
That makes the test_errors.sh command like the others, replacing
%B/test/Semantics/test_errors.sh with %S/test_errors.sh.
Also remove the OPTIONS: functionality as custom options can be included
in the RUN: command. And remove -I/../../include/flang as that is now
always included.

We have re-classified a subset of the regression tests as unit tests and
now we are porting the remaining ones.
Test discovery and running is now performed by lit rather than ctest.
The tests continue to use their original scripts with minor
modifications. Most of the changes were mechanical and so scripted.
A few changes were made by hand. Details
Manual:
* modfile09-*.f90 tests depend on being run together as some tests have
dependencies on modules created by other tests. This will need
separating out when porting away from test_modfile.sh, but for now,
added modfile09-*.f90 to the Inputs directory and added a single
tests modfile09.f90 to hold the run line.
* getdefinition03-a.f90 includes a non-test file getdefinition03-b.f90.
Manually edited the former to find the latter in Inputs so as to add
only one test.
* Same pattern for getsymbols03-{a,b}.f90
Auto:
* Remaining tests have a lit RUN line added to them based on the type
of test they are.
* Failing tests also have an XFAIL line added to them.
* Generic tests have their pre-existing RUN lines replaced with the
word "EXEC" to avoid conflict with the added lit RUN line.
