Move character tests to gtest, according to reviews from revision
D97349. Create a new temporary directory parallel to old runtime
unittests directory to facilitate the transition. Once patches for all
tests have been accepted using GTest, the old directory may be removed.
The new directory is required because LLVM's CMake unit test
infrastructure requires that the test depends on all source files in
the `CMAKE_CURRENT_SOURCE_DIR` directory.

Harmonize usage of LLVM components througout Flang.
Explicit LLVM Libs where used across several CMakeFIles, which led to
incompatibilities with LLVM shlibs.
Fortunately, the LLVM component system can be relied on to harmoniously handle
both cases.

The Fortran standard discusses BZ mode (treat blanks as zero digits)
explicitly in its effect on the editing of the digits prior to the
exponent part, but doesn't mention it in description of the
exponent part. Other compilers honor BZ mode in the exponent,
so we should do so too. So "1 e 1 " is 1.E11 in BZ mode.

It turns out that COMPLEX formatted input needs its own runtime APIs
so that null values in list-directed input skip the entire COMPLEX
datum rather than just a real or imaginary part thereof.

When FORMAT control reaches the final parenthesis and data items
remain, we advance a record and revert to the beginning of the
FORMAT for further items. But when the FORMAT contains any
nested parenthesized group of editing descriptors, possibly
repeated, reversion must be to the beginning of the last such
top-level parenthesized group, including its repetition count.

Fix fronted shared library builds by eliminating dependences of
the parser on other component libraries, moving some code around that
wasn't in the right library, and making some dependences
explicit in the CMakeLists.txt files. The lowering library

Add new unit tests for external Fortran I/O that drive the

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.

This patch replaces the occurrence of std::ostream by llvm::raw_ostream.
In LLVM Coding Standards[1] "All new code should use raw_ostream
instead of ostream".[1]
As a consequence, this patch also replaces the use of:
std::stringstream by llvm::raw_string_ostream or llvm::raw_ostream*
std::ofstream by llvm::raw_fd_ostream
std::endl by '\n' and flush()[2]
std::cout by llvm::outs() and
std::cerr by llvm::errs()
It also replaces std::strerro by llvm::sys::StrError** , but NOT in Fortran
runtime libraries
*std::stringstream were replaced by llvm::raw_ostream in all methods that
used std::stringstream as a parameter. Moreover, it removes the pointers to
these streams.

Some of the regression tests are C programs that act as test harnesses
for the compiler internals as opposed to being Fortran inputs to test
the compiler in action. The former style of tests are analog to LLVM's
unittests and will not use the lit framework.
