[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] Continue work on name resolution. In Symbol and Scope, use SourceName (== parser::CharBlock) in place of Name (== std::string) so that names in the symtab have provenance. We may ultimately have multiple source locations associated with a symbol. ImplicitRules: Add isImplicitNoneType and isImplicitNoneExternal flags. MessageHandler: Add methods to emit messages associated with source locations. Detect conflicting declarations of symbols (e.g. as subprogram and variable). Handle attribute statements like ASYNCHRONOUS statement: make sure the symbol is present and set the attribute on it. Check that these all have a type declared by the end of the specification part if IMPLICIT NONE. Find variables named in Variable and Expr nodes and check they have types declared if IMPLICIT NONE. Otherwise, make sure they are in the symtab and apply the implicit type rules at the end of the scope. Push a scope for MainProgram nodes and add a symbol for the name if it has one. Rename Scope::map_type to Scope::mapType Add tests for errors currently being detected. There is no framework for running them yet, just source files with the expected errors in comments.

integer :: x
[flang] Resolve array specifications of entities. Add ArraySpecVisitor to recognize the various forms of array specifications. They are tracked in arraySpec_ and attrArraySpec_. Both are needed because a declaration like `integer, dimension(4) :: x(2,2), y` has two different array-specs. The method DeclareEntity was extracted out to handle the common part for EntityDecl, ObjectDecl, and DimensionStmt. AllocatableStmt and TargetStmt are now handled through their contained ObjectDecl. The test resolve07 checks the interactions between these kinds of declarations. Rename ComponentArraySpec to ArraySpec as it doesn't just occur in components. Fix some 'begin' and 'end' methods to start with upper-case letters.

real :: x
[flang] Miscellaneous name resolution Handle BIND statement and PARAMETER statement. They are different from other attribute-setting statements so some refactoring of HandleAttributeStmt is required. And for PARAMETER, SetType needs to report an error if the implicitly determined type is changed later. This requires operator== on DeclTypeSpec. Resolve names in allocate statements, pointer assignment statements, substring expressions, and type parameter values.
