[flang][NFC] Simplify semantics test scripts 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.

[flang] Support interface blocks. Add subprogram symbols for each interface-body and set isInterface on them. Create a symbol with GenericDetails for each generic interface block and add interface specifications to the specific procedures of the generic. InterfaceVisitor takes care of this. Before processing the specification part of modules and subprograms, collect the names of module subprograms and internal subprograms and add them to the symbol table with SubprogramNameDetails. This allows us to reference them from interface blocks in the specification part. SubprogramNameDetails is converted to SubprogramDetails when the real subprogram is visited. This is achieved by setting subpNamesOnly_ and then walking the ModuleSubprogramPart or InternalSubprogramPart. Creating the symbol and scope for a module or subprogram now happens when the Module, SubroutineSubprogram, or FunctionSubprogram node is encountered so this can happen in the right order. Add BeginSubprogram and EndSubprogram to handle the parts in common between subprograms and interface specifications. Add GenericSpec to type.h to represent all possible generic specs. Only generic names are resolved so far. Add tests for new error messages. Change resolve02.f90 to reflect the new errors reported.

[flang] Add name resolution tests The Fortran source files in test/semantics all contain expected errors in comments. The script test_errors.sh compiles a file with 'f18 -fdebug-resolve-names -fparse-only' and compares the actual errors produced against the expected ones. The change to resolve15.f90 is necessary because test_errors.sh can't handle two expected errors for the same source line. A useful command to run these is 'ctest -R f90 --output-on-failure'. -R means only run tests with f90 in the name --output-on-failure prints the output of test_errors.sh when a test fails, showing the expected and actual messages that differ.

[flang] Name resolution for defined operators Instead of tracking just genericName_ while in a generic interface block or generic statement, now we immediately create a symbol for it. A parser::Name isn't good enough because a defined-operator or defined-io-generic-spec doesn't have a name. Change the parse tree to add a source field to GenericSpec. Use these as names for symbols for defined-operator and defined-io-generic-spec (e.g. "operator(+)" or "read(formatted)"). Change the source for defined-op-name to include the dots so that they can be distinguished from normal symbols with the same name (e.g. you can have both ".foo." and "foo"). These symbols have names in the symbol table like ".foo.", not "operator(.foo.)", because references to them have that form. Add GenericKind enum to GenericDetails and GenericBindingDetails. This allows us to know a symbol is "assignment(=)", for example, without having to do a string comparison. Add GenericSpecInfo to handle analyzing the various kinds of generic-spec and generating symbol names and GenericKind for them. Add reference to LanguageFeatureControl to SemanticsContext so that they can be checked during semantics. For this change, if LogicalAbbreviations is enabled, report an error if the user tries to define an operator named ".T." or ".F.". Add resolve-name-utils.cc to hold utility functions and classes that don't have to be in the ResolveNamesVisitor class hierarchy. The goal is to reduce the size of resolve-names.cc where possible.

[flang] Correctly resolve generics with forward references When a procedure is included by name in a generic (either with a procedure statement in a generic interface or with a generic statement) we can't immediately resolve it to a subprogram symbol. That is because the subprogram may be defined later in the specification part. Instead, collect the names (and whether they should be module procedures) and resolve them to symbols at the end of the specification part. Also detect duplicate names then. This is needed for module file reading as these forward references can occur there. Write generics to module file using generic statements. This allows us to include the access-spec.
