bugfix from premature push
Address review comments
Last fix(?)
Use %s formatting for CharBlocks and strings
Use new formatting and fix usage of std::forward<>()
Use forward_list rather than vector to save strings

Change statement semantics to continue with checks after an error
in expression analysis. This allows the compiler to report more
compilation errors. It requires that statement semantics not assume
that every parser::Expr has a valid evaluate::Expr.
For example, the test cases in coarrays02.f90 can now be moved to
coarrays01.f90. Previously the errors like "Must be a scalar value"
from ExprChecker prevented other errors from being detected by
CoarrayChecker.
Change to a stable sort of messages so that they come out in a
deterministic order. Otherwise when there are two errors at the
same location (e.g. line 71 of coarrays01.f90) the test can fail
randomly.

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.

FoldingContext is now part of SemanticsContext. It is created at the
beginning with a default-constructed CharBlock as the location in its
ContextualMessages.
Add PushLocation() to ContextualMessages to remember the previous source
location and set a new one. The old one is restored when the returned
object goes out of scope.
SemanticsContext is now the only state passed in to class ExprAnalyzer,
class Mutator, AnalyzeExpr(), AnalyzeExpressions().
Add Say() convenience functions for reporting errors to ExprAnalyzer.

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.

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.
