[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.

// to compiler parser machinery, and avoids features that require C++ runtime
