Rearrange the contents of __builtin_* module files a little and
make sure that semantics implicitly USEs the module __Fortran_builtins
before processing each source file. This ensures that the special derived
types for TEAM_TYPE, EVENT_TYPE, LOCK_TYPE, &c. exist in the symbol table
where they will be available for use in coarray intrinsic function
processing.
Update IsTeamType() to exploit access to the __Fortran_builtins
module rather than applying ad hoc name tests. Move it and some
other utilities from Semantics/tools.* to Evaluate/tools.* to make
them available to intrinsics processing.
Add/correct the intrinsic table definitions for GET_TEAM, TEAM_NUMBER,

This patch removes `f18`, a.k.a. the old driver. It is being replaced
with the new driver, `flang-new`, which has reached feature parity with
`f18` a while ago. This was discussed in [1] and also in [2].
With this change, `FLANG_BUILD_NEW_DRIVER` is no longer needed and is
also deleted. This means that we are making the dependency on Clang permanent
(i.e. it cannot be disabled with a CMake flag).
LIT set-up is updated accordingly. All references to `f18` or `f18.cpp`
are either updated or removed.
The `F18_FC` variable from the `flang` bash script is replaced with
`FLANG_FC`. The former is still supported for backwards compatibility.

Until now, `f18` would:
1. Use Flang to unparse the input files
2. Call an external Fortran compiler to compile the unparsed source
files (generated in step 1)
With this patch, `f18` will stop after unparsing the input source files,
i.e. step 1 above. The `flang` bash script will take care of step 2,
i.e. calling an external Fortran compiler driver to compile them. This
way:
* the functionality of `f18` is reduced - it will only drive Flang (as
opposed to delegating code-generation to an external tool on top of
this)
* we will able to switch between `f18` and `flang-new` for unparsing before
an external Fortran compiler is called for code-generation
The updated `flang` bash script needs to specify the output file when
using the `-fdebug-unparse` action. Both `f18` and `flang-new` have been
updated accordingly.
These changes were discussed in [1] as a requirement for replacing `f18`
with `flang-new`.

The build was putting .mod files for intrinsic modules in
tools/flang/include/flang but the install puts them in include/flang,
as does the out-of-tree build. This confused things for the driver.
This change makes the build consistent with the install and simplifies
the flang script accordingly.
Also, clean up the cmake commands for building the .mod files.

Now that semantics is working, the standard -fsyntax-only option of
GNU and Clang should be used as the name of the option that causes
f18 to just run the front-end. Support both options in f18, silently
accepting the old option as a synonym for the new one (as
preferred by the code owner), and replace all instances of the
old -fparse-only option with -fsyntax-only throughout the source base.

Flang has two CMake configurable header files that define compiler
version numbers:
* f18_version.h.in - only used in f18.cpp (uses version numbers from
LLVM's macro definitions)
* Version.inc.in - not currently used (uses version numbers hard-coded
in Flang's top CMake script)
Currently only f18_version.h.in provides version numbers consistent with
other subprojects in llvm-project. However, its location and name are
inconsistent with e.g. Clang. This patch merges the two headers
together:
* hard-coded version numbers in Flang's top CMake script are deleted
* Version.inc.in is updated to provide string versions of version
numbers (required by f18.cpp)
* f18_version.h.in is deleted as it's no longer needed

The flang wrapper script that was created as bin/flang in an in-tree
build did not have a correct -intrinsic-module-directory option.
It was correct for out-of-tree builds and for both kinds of installs.
The fix is to pick the correct directory based on what exists.
The script is no longer configured by cmake (just copied) so that
mechanism can be deleted from the cmake file.

Under current configuration, the permission of `flang` after installation is 700.
This could bring a problem for system administrators who build and install flang
for other users, which only the user who builds LLVM can execute it, and others
can not. In this patch, the explicit permission setting in the `install` command
is removed, and let CMake determine what perssion to be used like other components.

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 re-ordering allows building f18 with shared library using and LLVM build
with static libraries.
This reordering (that also made sens form an alphabetical point of view)
works here to do such "shared+archive" compiling because the current
dependency on LLVM is simple (only one f18 lib + an executable depends on LLVM).
As soon as two f18 libraries will depend on LLVM, one will have to use an LLVM
version built with -DBUILD_SHARED_LIBS=On if one wants to use this option
to compile f18.

The Pre-FIR Tree structure is a transient data structure that
is meant to be built from the parse tree just before lowering to
FIR and that will be deleted just afterwards. It is not meant to perfrom
optimization analysis and transformations. It only provides temporary
information, such as label target information or parse tree parent nodes,
that is meant to be used to lower the parse tree structure into
FIR operations.
A PFTBuilder class builds the Pre-Fir Tree from the parse-tree.
A pretty printer is available to visualize this data structure.
- Lit tests are added to:
1. that the PFT tree structure is as expected
2. that the PFT captures all intented nodes
- Cmake changes: Prevent warnings inisde LLVM headers when compiling flang
The issue is that some LLVM headers define functions where the usage of
the parameters depend on environment ifdef. See for instance Size in:
5f940220bf/llvm/include/llvm/Support/Compiler.h (L574)
Because flang is build with -Werror and -Wunused-parameter is default in
clang, this may breaks build in some environments (like with clang9 on macos).
A solution would be to add -Wno-unused-parameter to flang CmakLists.txt,
but it is wished to keep this warning on flang sources for quality purposes.
Fixing LLVM headers is not an easy task and `[[maybe_unused]]` is C++17 and
cannot be used yet in LLVM headers.
Hence, this fix simply silence warnings coming from LLVM headers by telling
CMake they are to be considered as if they were system headers.
- drone.io changes: remove llvm 6.0 from clang config in drone.io and link
flang with libstdc++ instead of libc++
llvm-dev resolved to llvm-6.0 in clang builds on drone.io. llvm 6.0 too old.
LLVM packages are linked with libstdc++ standard library whereas libc++ was
used for flang. This caused link time failure when building clang. Change
frone.io to build flang with libc++.
