[flang] Update the regression tests to use the new driver when enabled This patch updates most of the remaining regression tests (~400) to use `flang-new` rather then `f18` when `FLANG_BUILD_NEW_DRIVER` is set. This allows us to share more Flang regression tests between `f18` and `flang-new`. A handful of tests have not been ported yet - these are currently either failing or not supported by the new driver. Summary of changes: * RUN lines in tests are updated to use `%flang_fc1` instead of `%f18` * option spellings in tests are updated to forms accepted by both `f18` and `flang-new` * variables in Bash scripts are renamed (e.g. F18 --> FLANG_FC1) The updated tests will now be run with the new driver, `flang-new`, whenever it is enabled (i.e when `FLANG_BUILD_NEW_DRIVER` is set). Although this patch touches many files, vast majority of the changes are automatic: ``` grep -IEZlr "%f18" flang/test/ \| xargs -0 -l sed -i 's/%f18/%flang_fc1/g ``` Differential Revision: https://reviews.llvm.org/D100309 2021-04-12 20:27:49 +08:00			`!

[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.

[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.
