[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] Rewrite function calls to array element references parse-tree.h, parse-tree.cc: Add FunctionReference::ConvertToArrayElementRef() to convert a function reference to an array element reference. Factor out MakeArrayElementRef() to use in ConvertToArrayElementRef() and also in converting statement functions to array element assignments. resolve-names.cc: Recognize references to functions and subroutines and add symbols for them. Detect declaration conflicts from these and check `IMPLICIT NONE(EXTERNAL)`. rewrite-parse-tree.cc: Find function references that need to be converted and rewrite them.

[flang] Add support for BLOCK construct A `BLOCK` statement opens a new scope. It is different from other scopes in that implicitly typed entities are defined in the enclosing non-block scope, not immediately in the block. This means that `IMPORT` statements can cause them to be hidden. Check that blocks can't have `IMPLICIT` statements in them. It is simpler for the parser not to deal with the different between a specification-part and a block-specification-part. Change `ImplicitRules` to have a parent that is consulted when there isn't an answer in the current one. For an interface body that does not happen but for all other nested scopes it does. This parent link eliminates the need for the `implicitRules_` stack. Make `isImplicitNoneType_` and `isImplicitNoneExternal_` optional: not set means look in parent. Fixes flang-compiler/f18#71. Remove `CurrNonTypeScope()` and put the logic in `Symbol::FindSymbol`.
