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.

This change prepares usage of lipgmath description in lowering.
- Removes the static variable templates that were used to abstract
libpgmath description
- Move the description to pgmath.h.inc header and rework the macros
so that they can both be used to declare pgmath functions and use
them.
The way they are to be used is left to pgmath.h.inc user that
must define PGMATH_USE_XX macros that will be called for all pgmath
functions in pgmath.h.inc.
- In intrinsic-library.cpp define PGMATH_USE_XX macro callbacks in
order to capture function pointers to pgmath functions as well as
a description of their type. This will be used for constant folding
using pgmath.
- Change atan/atan2 handling to use atan2 instead of atan when there are two
arguments because it is easier to handle in the runtime description.
Also fixes lipgmath linking regression after D78215 cmake changes.
This change is motivated by the need to use a similar pgmath
description in lowering. The difference is that no function pointers will
be taken there, and instead only the function name and type are needed.

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:
Defines a representation for the initialized memory image of
a variable. This image is populated by DATA statement
processing as designator elements are put into correspondence
with values, then converted into an initializer in the symbol
table so that lowering can pass the initial image to the
code generator.

Summary:
Add code to resolve constant Designators at compilation time
into a base Symbol, byte offset, and field size. This is used in
later DATA statement processing to identify the static storage being
initialized by each object in a DATA statement. Also implement
the reverse mapping so that Designators can be reconstructed for
use in error messages about (e.g.) duplicate initializers.

When building flang with LLVM HEAD, the unittests fail to link with ld.bfd or
ld.gold due to a linker ordering issue. Adding libSemantics as a dependency to
libEvaluate seems to fix that issue.

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.
