At least one other Fortran compiler supports the use of unrestricted intrinsic
functions as specific procedures in generic interfaces, and the usage seems
to be both useful and unambiguous. Support it with a portability warning.
Fixes llvm-test-suite/Fortran/gfortran/regression/pr95500.f90.

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
```

2 Bug fixes:
- Do not resolve procedure as intrinsic if they appeared in an
EXTERNAL attribute statement (one path was not considering this flag)
- Emit an error if a procedure resolved to be an intrinsic function
(resp. subroutine) is used as a subroutine (resp. function).
Lowering was attempted while the evaluate::Expression for the
call was missing without any errors.
1 behavior change:
- Do not implicitly resolve subroutines (resp. functions) as intrinsics
because their name is the name of an intrinsic function (resp.
subroutine). Add justification in documentation.
