[Flang] Ported test_errors.sh to Python 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.

[flang] Clause 13 (Input/output editing) syntax and semantic checking (flang-compiler/f18#498) * Clause 13 (Input/output editing) syntax and semantic checking Diagnose: - all clause syntax errors (independent of normal parsing) - all clause constraints - use of non-standard extensions under -Mstandard - obvious program requirement violations The code: - is invoked for both format statement and I/O statement constant formats - should be useable by the runtime I/O library for runtime formats - is able to recover from errors - is able to diagnose multiple errors in a single format - has accurate markers for errors - can process (fixed character size) Hollerith strings - generates reasonable error messages for known error scenarios - should not require C++ run-time library support The code is templatized for use with fixed size character kind={1,2,4} input, but only the kind=1 variant is actually exercised. * Review update. * Review update. * Review update. * Improve error processing of unterminated formats.
