[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] More coarray name resolution and semantic checks Add CoarrayChecker to check for valid team-value in CHANGE TEAM, SYNC TEAM, and image selector. Check that coarray names and selector names are distinct in CHANGE TEAM. Resolve the variable in a coarray-association. Create a scope for the construct entities of a CHANGE TEAM construct. Add ResolveSelector to resolve a parser::Selector into an Expr and optional variable name (and a source location for messages). Make use of ResolveSelector to handle coarray-association, as well as it's previous use in associate-stmt. Improve the check for C1157 in select-type-stmt and add a test. Add a test for "Associate name must have a type". Move ResolveName, ResolveDataRef, etc. from ResolveNamesVisitor to DeclarationVisitor so that they are available in ConstructVisitor as well. Add ResolveVariable and ResolveDesignator. In the parse tree, change TeamValue from a type alias to a wrapper class. We already had a wrapper class anyway, ImageSelectorSpec::Team, so the new TeamValue can be used instead. This allows the member of ImageSelectorSpec to be treated like other occurrences of TeamValue.
