This patch adds a few new member methods in the `PluginParseTreeAction`
frontend action base class. With these new methods, the plugin API
becomes independent of the driver internals. In particular, plugin
writers no longer require the `CompilerInstance.h` header file to access
various driver data structures (instead, they can use newly added
hooks).
This change is desirable as `CompilerInstance.h` includes various
headers from Clang (both explicitly and implicitly). Some of these
header files are generated at build time (through TableGen) and
including them creates a dependency on some of Clang's build targets.
However, plugins in Flang should not depend on Clang build targets.
Note that plugins might still work fine most of the time, even without
this change and without adding Clang build targets as dependency in
plugin's CMake definition. Indeed, these Clang build targets are often
generated early in the build process. However, that's not guaranteed and
we did notice that on occasions plugins would fail to build.

This patch adds parser nodes for each indivudual section in sections
construct. This should help with the translation to FIR. `!$omp section`
was not recognized as a construct and hence needed special handling.
`OpenMPSectionsConstruct` contains a list of `OpenMPConstruct`. Each
such `OpenMPConstruct` wraps an `OpenMPSectionConstruct`
(section, not sections). An `OpenMPSectionConstruct` is a wrapper around
a `Block`.

Currently, everything that includes "flang/Parser/parse-tree.h" in Flang
depends on the `gen_acc` and `gen_omp` CMake targets (these targets
generate include files that are used in "parse-tree.h"). The examples in
Flang do use this header file and hence also depend on
`gen_acc`/`gen_omp`. This patch updates relevant CMake scripts
accordingly.
I've also taken the liberty to rename some of the example files so that
their names follow LLVM's coding guidelines.

The flang plugin ``flang-omp-report`` takes one fortran file in and returns a
YAML report file of the input file. This becomes an issue when you want to
analyse an entire project into one final report.
The purpose of this Python script is to generate a final YAML
report from all of the files generated by ``flang-omp-report``. The report can
have (currently) 2 formats; summary and log. Summary focuses on "summarizing"
all constructs and there clauses from all YAML files with a corresponding "count"
for each. Log instead combines the generated YAML files into one report in a
"cleaner" format. (Pseudo) Examples can be found for both formats at the top of
the script.

In a "Worksharing-loop construct", one can add a nowait clause at the end
of the loop (i.e. at the loop tail). This clause wasn't associated with
the corresponding loop when originally worked on in flang-omp-report.
Note that this refers to parsing and parse-tree generation. To work
around it, it was needed to track such clauses and the loops.
This should no longer be required (and in fact no longer works) and so
was removed. This results in 'curLoopLogRecord' and 'loopLogRecordStack' and
all references to them being removed. This also allows for
'constructClauses' to be swapped from std::deque to llvm::SmallVector.
Lastly a new test has been added testing the "nowait" clauses in a
variety of ways.

This patch replaces the uses of std::map with llvm::DenseMap in the
flang-omp-report plugin. It also removed the 'constructClauseCount' map
due to no longer being needed after the plugin was stripped down.
This is a one of several patches focusing on switching containers from STL to LLVM's ADT library.

This plugin parses Fortran files and creates a
YAML report with all the OpenMP constructs and
clauses seen in the file.
The following tests have been modified to be
compatible for testing the plugin, hence why
they are not reused from another directory:
- omp-atomic.f90
- omp-declarative-directive.f90
- omp-device-constructs.f90
The plugin outputs a single file in the same
directory as the source file in the following format:
`<source-file-name>.yaml`
Building the plugin:
`ninja flangOmpReport`
Running the plugin:
`./bin/flang-new -fc1 -load lib/flangOmpReport.so -plugin flang-omp-report -fopenmp <source_file.f90>`

Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.
flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.

Replacing Hello World example Plugin with one that counts and prints the names of
functions and subroutines.
This involves changing the `PluginParseTreeAction` Plugin base class to
inherit from `PrescanAndSemaAction` class to get access to the Parse Tree
so that the Plugin can walk it.
Additionally, there are tests of this new Plugin to check it prints the correct
things in different circumstances.

Introducing a plugin API and a simple HelloWorld Plugin example.
This patch adds the `-load` and `-plugin` flags to frontend driver and
the code around using custom frontend actions from within a plugin
shared library object.
It also adds to the Driver-help test to check the help option with the
updated driver flags.
Additionally, the patch creates a plugin-example test to check the
HelloWorld plugin example runs correctly. As part of this, a new CMake
flag (`FLANG_BUILD_EXAMPLES`) is added to allow the example to be built
and for the test to run.
This Plugin API has only been tested on Linux.
