Tim Keith daa0b054ba [flang] Change formatting of common::visitors{}
Including a comma after the last lambda in a `common::visitors{}` list
causes clang-format to do a better job of formatting them.

Add that recommendation to C++style.md, insert the missing commas,
and reformat the changed files.

Tim Keith f62f8b655d [flang] Implement reading of module files
When a use-stmt is encountered for a module that isn't in the global
scope, search for and read the appropriate `.mod` file. To perform the
search, pass the search directories in to ResolveNames.

For modules that were read from `.mod` files, we have to keep the cooked
source from being deleted so that the names so that references to names
stay valid. So we store the cooked source in the Scope of the module as
a `unique_ptr`.

Add `Symbol::Flag::ModFile` to distinguish module symbols that were read
from a `.mod` file rather than from the current compilation. Use it to
prevent writing those back out.

Fix test_errors.sh to run the compiler in the temp subdirectory --
otherwise tests could be affected by `.mod` files left from previous
tests.

peter klausler 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.

peter klausler 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.
