[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] Fix bug accessing implicit variable in specification expression A specification expression can reference an implicitly declared variable in the host procedure. Because we have to process specification parts before execution parts, this may be the first time we encounter the variable. We were assuming the variable was implicitly declared in the scope where it was encountered, leading to an error because local variables may not be referenced in specification expressions. The fix is to tentatively create the implicit variable in the host procedure because that is the only way the specification expression can be valid. We mark it with the flag `ImplicitOrError` to indicate that either it must be implicitly defined in the host (by being mentioned in the execution part) or else its use turned out to be an error. We need to apply the implicit type rules of the host, which requires some changes to implicit typing. Variables in common blocks are allowed to appear in specification expressions (because they are not locals) but the common block definition may not appear until after their use. To handle this we create common block symbols and object entities for each common block object during the `PreSpecificationConstruct` pass. This allows us to remove the corresponding code in the main visitor and `commonBlockInfo_.curr`. The change in order of processing causes some different error messages to be emitted. Some cleanup is included with this change: - In `ExpressionAnalyzer`, if an unresolved name is encountered but no error has been reported, emit an internal error. - Change `ImplicitRulesVisitor` to hide the `ImplicitRules` object that implements it. Change the interface to pass in names rather than having to get the first character of the name. - Change `DeclareObjectEntity` to have the `attrs` argument default to an empty set; that is the typical case. - In `Pre(parser::SpecificationPart)` use "structured bindings" to give names to the pieces that make up a specification-part. - Enhance `parser::Unwrap` to unwrap `Statement` and `UnlabeledStatement` and make use of that in PreSpecificationConstruct.

[flang] Handle DATA initialization of EQUIVALENCE'd objects Objects that are storage associated by EQUIVALENCE and initialized with DATA are initialized by creating a compiler temporary data object in the same scope, assigning it an offset, type, and size that covers the transitive closure of the associated initialized original symbols, and combining their initializers into one common initializer for the temporary. Some problems with offset assignment of EQUIVALENCE'd objects in COMMON were exposed and corrected, and some more error cases are checked. Remove obsolete function. Small bugfix (nested implied dos). Add a test. Fix struct/class warning. Differential Revision: https://reviews.llvm.org/D85560
