[flang] A rework of the cmake build components for in and out of tree builds. In general all the basic functionality seems to work and removes some redundancy and more complicated features in favor of borrowing infrastructure from LLVM build configurations. Here's a quick summary of details and remaining issues: * Testing has spanned Ubuntu 18.04 & 19.10, CentOS 7, RHEL 8, and MacOS/darwin. Architectures include x86_64 and Arm. Without access to Window nothing has been tested there yet. * As we change file and directory naming schemes (i.e., capitalization) some odd things can occur on MacOS systems with case preserving but not case senstive file system configurations. Can be painful and certainly something to watch out for as any any such changes continue. * Testing infrastructure still needs to be tuned up and worked on. Note that there do appear to be cases of some tests hanging (on MacOS in particular). They appear unrelated to the build process. * Shared library configurations need testing (and probably fixing). * Tested both standalone and 'in-mono repo' builds. Changes for supporting the mono repo builds will require LLVM-level changes that are straightforward when the time comes. * The configuration contains a work-around for LLVM's C++ standard mode passing down into Flang/F18 builds (i.e., LLVM CMake configuration would force a -std=c++11 flag to show up in command line arguments. The current configuration removes that automatically and is more strict in following new CMake guidelines for enforcing C++17 mode across all the CMake files. * Cleaned up a lot of repetition in the command line arguments. It is likely that more work is still needed to both allow for customization and working around CMake defailts (or those inherited from LLVM's configuration files). On some platforms agressive optimization flags (e.g. -O3) can actually break builds due to the inlining of templates in .cpp source files that then no longer are available for use cases outside those source files (shows up as link errors). Sticking at -O2 appears to fix this. Currently this CMake configuration forces this in release mode but at the cost of stomping on any CMake, or user customized, settings for the release flags. * Made the lit tests non-source directory dependent where appropriate. This is done by configuring certain test shell files to refer to the correct paths whether an in or out of tree build is being performed. These configured files are output in the build directory. A %B substitution is introduced in lit to refer to the build directory, mirroring the %S substitution for the source directory, so that the tests can refer to the configured shell scripts.

[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.
