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
does not yet build as a shared library due to some undefined
names.

Summary:
This patch is removing the custom enumeration for OpenMP Directives and Clauses and replace them
with the newly tablegen generated one from llvm/Frontend. This is a first patch and some will follow to share the same
infrastructure where possible. The next patch should use the clauses allowance defined in the tablegen file.

Summary:
Initially on github I worked on semantic checks.Then I tried some compile-time
test of the rank value, they were failing as there were no symbols
generated for them inside SELECT RANK's scope.So I went further to
add new symbol in each scope, also added the respective 'rank: '
field for a symbol when we dump the symboltable. I added a field to
keep track of the rank in AssocEntityDetails class.This caused shape
analysis framework to become inconsistent. So shape analysis framework
was updated to handle this new representation.
* I added more tests for above changes.
* On phabricator I addressed some minor changes.
* Lastly I worked on review comments.

Summary:
Add size and offset properties to symbols, representing their byte size
and offset within their enclosing scope.
Add size and align properties to scopes so that they are available for
scopes representing derived types.
Add ComputeOffsets pass over the symbol table to fill in those fields.
Compute descriptor size based on rank and length parameters. Extract
DerivedTypeSpec::NumLengthParameters from DynamicType::RequiresDescriptor
to share the code.
Add Scope::GetSymbols to get symbols in canonical order.
compute-offsets.cpp and mod-file.cpp both need to process symbols in the
order in which they are declared. Move the collecting of those symbols
into Scope so that it can be shared.
Add symbol size and offset to output of `-fdebug-dump-symbols` and use
that in some tests.
Still to do:
- make size and alignment rules configurable based on target
- use offsets to check EQUIVALENCE statements

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.
