The PFT has been updated to support Fortran 77.
clang-tidy cleanup.

Add the following options:
* -fdebug-measure-parse-tree
* -fdebug-pre-fir-tree
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.

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.
review comments:
[review D80449][NFC] make PFT ParentVariant a ReferenceVariant
ReferenceVariant had to be slightly updated to also support
non constant references (which is required for ParentType).
[review D80449] extend Variable implementation beyond a comment
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.
