Similarly to LBOUND in https://reviews.llvm.org/D123237, fix UBOUND() folding
for constant arrays (for both w/ and w/o DIM=): convert
GetConstantArrayLboundHelper into common helper class for both lower/upper
bounds.

Set LBOUND() constant folding for parentheses expr. as ones
Array bounds should not propagate throught omitted bounds specifications or
temporary variables - fix constant folding in case of Parentheses<T> expression
by explicitly returning array of ones (or scalar in case of DIM=).
Add set of tests for (x) bounds checks (w/ and w/o 'parameter' arrays)

Previously constant folding uses 'dim' without checks which leads to ICE if we
do not have DIM= parameter. And for inputs without DIM= we need to form an
array of rank size with computed bounds instead of single value.
Add additional PackageConstant function to simplify 'if (dim)' handling since we
need to distinguish between scalar initialization in case of DIM= argument and
rank=1 array.
Also add a few more tests with 'parameter' type to verify folding for constant
arrays.

Similarly to LBOUND in https://reviews.llvm.org/D121488, UBOUND must
return zero for an empty dimension, no matter the specification
expression.
Add a GetUBOUND method to be used in expression rewrite that prevents
folding UBOUND to a bound specification expression if the extent is
not a compile time constant.
Fold the case where the extents is known to be zero (and also deal with
this case in LBOUND since we can and should to comply with constant
expression requirements).

explicit expression might appear in a declaration or arrive in
a descriptor.

To enable Flang testing on Windows,
shells scripts have to be ported to Python.
The following changes have been made:
Ported `test_folding.sh` to Python;
Additional changes to the tests themselves
to use the new script.
LIBPGMATH support for testing
not available at this point.

Allow the lit test suite to run under Windows. This encompasses the following changes:
* Define `lit_tools_dir` for flang's test configuration
* Replace `(<command> || true)` idiom with `not <command>`
* Add `REQUIRES: shell` on tests that invoke a shell script

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
```
Differential Revision: https://reviews.llvm.org/D100309
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.
