Replaced std::exit() with return Carbon::ErrorOr for expected errors like invalid syntax ( #1120 )
...
* Replaced std::exit() with return llvm::Expected/llvm::Error<T> for expected errors like invalid syntax.
* Use llvm::formatv() for formatting lexer error messages.
x
* Addresed merge errors.
* Fixed impl scope.
* Made ErrorBuilder::operator<< nodiscard, to catch code forgetting 'return' in 'return FATAL_COMPILATION_ERROR()'.
* FatalComplationError() -> ParseAndLexContext::RecordLexerError().
Other usages of ERROR_TOKEN in lexer.lpp were actually supposed to be END_OF_FILE.
* Update executable_semantics/syntax/parse_and_lex_context.h

Pass the flag instead of using a global. ( #893 )
...
Arguably missed in #769
Note, this is reminding me we have more class members to rename for `_`, but I felt it's best to use the new naming instead of adding more to clean up.

Rename Ptr<T> to Nonnull<T*> ( #832 )
...
Note that ptr.h also includes an enable_if change, to help avoid https://bugs.llvm.org/show_bug.cgi?id=51881

Remove global_arena ( #814 )
...
With this, only main.cpp instantiates an arena. Maybe we'll want to split that up more later (e.g., so that the runtime interpreter uses its own arena), but given the intent to have type-checking update the AST, I thought this was a reasonable approach for now in order to avoid ownership complexities.
Fixes #769

Add syntax for package and library ( #792 )
...
Doesn't add much logic, only takes advantage of parser structure for the ordering enforcement.
Note import_nonexistent tests should probably fail, but writing import tests needs a chain of functionality, and I figured I'd just start adding some to validate the syntax (not adding existent imports because that'd require multi-file structure).

Move ExecProgram to interpreter/ ( #802 )
...
Seems to make sense since it's the only interpreter/ dependency in syntax/ right now, so this feels like untangling deps.
Fixes #371
