75b29335ab [flang] Clean out obsolete parsing code. Handle !cdir$ fixed and free in parser. 
Work on scanning compiler directive lines.

Fix glitch in earlier change to parse-state.h.

Add ClassifyLine(), simplify some token sequence data lifetimes and interfaces.

Handle continued directives.  Obey !DIR$ FIXED and FREE in prescanner.

Some refactoring of TokenSequence API, then support initial directives (FIXED, FREE, IGNORE_TKR).

Fix !DIR$ IGNORE_TKR syntax, manual was wrong.

Debugging directive scanning & parsing.

Profiling-directed speed-up - do not map cooked source locations to Provenance until a Message is emitted.  Turn some non-nullable pointers into references.

Debugging.

Handle !DIR$ IVDEP too, it is in a test.

Accept directives in the execution part.

424ec7b35b [flang] Handle empty files gracefully. 
Create interval.h.  Use std::size_t instead of bare size_t.  Redefine parser::Name to not be just a bare string.

Break out and rename CharBlock from token-sequence.h for use in the parse tree.

Incremental replacement of name strings with pointers to cooked characters.

Fix case sensitivity problem.

Use new CharBlock encoding to replace strings for real literal constants.

Normalized cooked character stream to lower case.

Simplify parsing now that cooked stream is lower case.  Replace Keyword in parse tree.

Add static_asserts to || and recovery parsers to enforce same result types.

Remove needless TODO comment inserted earlier.

Fix case conversion on prefixed character literals (f90_correct/dc04.f90).

Use CharBlock in user-state.h.

Complete transition from nextChar to nextCh (i.e., always use pointers).

Document extensions.  Begin work on compiler directive lines.

More documentation work.

Reformat prescan.cc.

More work on compiler directive scanning.
