This patch brings in code which can lower a Fortran intrinsic to
a runtime call or an llvm intrinsic. For math intrinsics the
runtime call is to the `math` or `pgmath` library. Non-math
intrinsics are covered by the Flang runtime. A distance computation
mechanism is introduced to find the runtime function that closely
matches the types of the intrinsic call.
In this patch, the `abs` intrinsic is lowered in the following way,
-> Integer version is lowered as a group of MLIR/FIR operations
-> Real version is lowered to llvm intrinsics
-> Complex version is lowered to the `math_hypot` runtime function

This patch brings in some initial changes for lowering Fortran
intrinsics. Intrinsics are generally lowered to a mix of FIR and
MLIR operations, runtime calls or LLVM intrinsics. This patch
particularly brings in the lowering of the Fortran `andi` intrinsic
to `arith.andi` in MLIR.
The significant changes are in ConvertExpr.cpp and IntrinsicCall.cpp.
Intrinsic functions occur as part of expressions. Lowering deals with this
in ConvertExpr.cpp in `genval(const Fortran::evaluate::FunctionRef<A> &funcRef)`.
The code in the above mentioned function kicks of a sequence of calls
that ultimately results in a call to the `genIand ` function in
IntrinsicCall.cpp which creates the MLIR `arith.andi` operation.
A few tests are also included.
Note: Generally intrinsics like `iand` can occur in array (elemental)
context, but since that part is not fully supported in lowering, tests
are only added for the scalar context.

This patch adds support for lowering the Fortran goto statement from
parse-tree to MLIR. The goto statement in Fortran is a form of
unstructured control flow. The statement transfers control to the
code starting at the label specified in the statement. This can be
faithfully represented in MLIR by a branch instruction.
To assist the lowering of code with unstructured control flow, blocks
are created in advance and associated with the relevant pre-fir tree
evaluations.
This is part of the upstreaming effort from the fir-dev branch in [1].

This patch lowers STOP statement without arguments
and ERROR STOP. STOP statement with arguments lowering will
come in later patches ince it requires some expression lowering
to be added.
STOP statement is lowered to a runtime call.
Also makes sure we are creating a constant in the MLIR arith constant.

This patch enable lowering from Fortran to FIR for a basic empty
program. It brings all the infrastructure needed for that. As discussed
previously, this is the first patch for lowering and follow up patches
should be smaller.
With this patch we can lower the following code:
```
program basic
end program
```
To a the FIR equivalent:
```
func @_QQmain() {
return
}
```
Follow up patch will add lowering of more complex constructs.

With this change, the following invocations will be treated as errors
(multiple actions are specified):
```
$ flang-new -fc1 -E -fsyntax-only file.95
$ flang-new -fc1 -fsyntax-only -fdebug-dump-symbols file.95
```
In the examples above it is not clear whether it is `-fsyntax-only` or
the other action that is run (i.e. `-E` or `-fdebug-dump-symbols`). It
makes sense to disallow such usage. This should also lead to cleaner and
clearer tests (the `RUN` lines using `%flang_fc1` will only allow one
action).
This change means that `flang-new -fc1` and `clang -cc1` will behave
differently when multiple action options are specified. As frontend
drivers are mostly used by compiler developers, this shouldn't affect or
confuse the compiler end-users. Also, `flang-new` and `clang` remain
consistent.
Tests are updated accordingly. More specifically, I've made sure that
every test specifies only one action. I've also taken the opportunity to
simplify "multiple-input-files.f90" a bit.

[NFC] As part of using inclusive language within the llvm project, this patch:
- replaces master with main in C++style.md to match the renaming of the master
branch,
- removes master from `FortranIR.md` where it is superfluous,
- renames a logical variable in `pre-fir-tree04.f90` containing master.

This patch updates most of the remaining regression tests (~400) to use
`flang-new` rather then `f18` when `FLANG_BUILD_NEW_DRIVER` is set.
This allows us to share more Flang regression tests between `f18` and
`flang-new`. A handful of tests have not been ported yet - these are
currently either failing or not supported by the new driver.
Summary of changes:
* RUN lines in tests are updated to use `%flang_fc1` instead of `%f18`
* option spellings in tests are updated to forms accepted by both `f18` and
`flang-new`
* variables in Bash scripts are renamed (e.g. F18 --> FLANG_FC1)
The updated tests will now be run with the new driver, `flang-new`,
whenever it is enabled (i.e when `FLANG_BUILD_NEW_DRIVER` is set).
Although this patch touches many files, vast majority of the changes are
automatic:
```
grep -IEZlr "%f18" flang/test/ | xargs -0 -l sed -i 's/%f18/%flang_fc1/g
```

In https://reviews.llvm.org/D98283, the RUN line in pre-fir-tree04.f90
was updated to use `%flang_fc1` instead of `%f18` (so that the test is
shared between the old and the new driver). Unfortunately, the new
driver does not know yet how to find standard intrinsics modules. As a
result, the test fails when `FLANG_BUILD_NEW_DRIVER` is set to On.
I'm restoring the original RUN line. This is rather straightforward, so
sending without a review. This should make Flang builders happy.
The PFT has been updated to support Fortran 77.

Summary of changes:
- Add 2 new frontend actions: DebugMeasureParseTreeAction and DebugPreFIRTreeAction
- Add MeasurementVisitor to FrontendActions.h
- Make reportFatalSemanticErrors return true if there are any fatal errors
- Port most of the `-fdebug-pre-fir-tree` tests to use the new driver if built, otherwise use f18.

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.

OpenACC combined construct can have an optional end directive. This patch handle this
case in the parsing/unparsing with a canonicalization step. Unlike OmpEndLoopDirective,
this doesn't need a special treatment in the pre-fir tree as there is no clause attached to
a AccEndCombinedDirective.

structure for upstreaming to llvm-project.
These files have had many changes since they were originally upstreamed.
Some of the changes are cosmetic. Most of the functional changes were
done to support the lowering of control-flow syntax from the front-end
parse trees to the FIR dialect.
This patch is meant to be a reviewable size. The functionality it
provides will be used by code yet to be upstreamed in lowering.

There were several different ways of handling the option to f18 to
find predefined modules:
- test_errors.sh was created by cmake substituting
FLANG_INTRINSIC_MODULES_DIR into test_errors.sh.in
- some tests used the flang script which has the option built it
- some tests used %f18_with_includes which was replaced by the path
to f18 plus the -I option
- some included -I../../include/flang in their run command
To make this more consistent, change %f18 to include the
-intrinsic-module-directory option and use it everywhere, including
to replace %flang and %f18_with_includes. This requires changing all
of the invocations of the test scripts to put %f18 at the end so that
it can expand to more than one argument.
This eliminates the need to generate test_errors.sh which means we
don't need flang/test/Semantics/CMakeLists.txt or the %B substitution.
That makes the test_errors.sh command like the others, replacing
%B/test/Semantics/test_errors.sh with %S/test_errors.sh.
Also remove the OPTIONS: functionality as custom options can be included
in the RUN: command. And remove -I/../../include/flang as that is now
always included.

We have re-classified a subset of the regression tests as unit tests and
now we are porting the remaining ones.
Test discovery and running is now performed by lit rather than ctest.
The tests continue to use their original scripts with minor
modifications. Most of the changes were mechanical and so scripted.
A few changes were made by hand. Details
Manual:
* modfile09-*.f90 tests depend on being run together as some tests have
dependencies on modules created by other tests. This will need
separating out when porting away from test_modfile.sh, but for now,
added modfile09-*.f90 to the Inputs directory and added a single
tests modfile09.f90 to hold the run line.
* getdefinition03-a.f90 includes a non-test file getdefinition03-b.f90.
Manually edited the former to find the latter in Inputs so as to add
only one test.
* Same pattern for getsymbols03-{a,b}.f90
Auto:
* Remaining tests have a lit RUN line added to them based on the type
of test they are.
* Failing tests also have an XFAIL line added to them.
* Generic tests have their pre-existing RUN lines replaced with the
word "EXEC" to avoid conflict with the added lit RUN line.
