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,
and THIS_IMAGE to exercise the built-in TEAM_TYPE as an argument and
as a result.
Add/correct/extend tests accordingly.

To enable Flang testing on Windows, shell scripts have to be ported to Python. In this patch the "test_errors.sh" script is ported to python ("test_errors.py"). The RUN line of existing tests was changed to make use of the python script.
Used python regex in place of awk/sed.

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
```

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.

Summary:
Most of these checks were already implemented, and I just added references to
them to the code and tests. Also, much of this code was already
reviewed in the old flang/f18 GitHub repository, but I didn't get to
merge it before we switched repositories.
I implemented the check for C747 to not allow coarray components in derived
types that are of type C_PTR, C_FUNPTR, or type TEAM_TYPE.
I implemented the check for C748 that requires a data component whose type has
a coarray ultimate component to be a nonpointer, nonallocatable scalar and not
be a coarray.
I implemented the check for C750 that adds additional restrictions to the
bounds expressions of a derived type component that's an array.
These bounds expressions are sepcification expressions as defined in
10.1.11. There was already code in lib/Evaluate/check-expression.cpp to
check semantics for specification expressions, but it did not check for
the extra requirements of C750.
C750 prohibits specification functions, the intrinsic functions
ALLOCATED, ASSOCIATED, EXTENDS_TYPE_OF, PRESENT, and SAME_TYPE_AS. It
also requires every specification inquiry reference to be a constant
expression, and requires that the value of the bound not depend on the
value of a variable.
To implement these additional checks, I added code to the intrinsic proc
table to get the intrinsic class of a procedure. I also added an
enumeration to distinguish between specification expressions for
derived type component bounds versus for type parameters. I then
changed the code to pass an enumeration value to
"CheckSpecificationExpr()" to indicate that the expression was a bounds
expression and used this value to determine whether to emit an error
message when violations of C750 are found.
I changed the implementation of IsPureProcedure() to handle statement
functions and changed some references in the code that tested for the
PURE attribute to call IsPureProcedure().
I also fixed some unrelated tests that got new errors when I implemented these
new checks.
