Jon Ross-PerkinsandChandler Carruth 352fec1885 Add some coarse debug information to semantics. (#2382) 
Example stack:

```
1.	node_stack_:
	0.	FunctionDefinitionStart
	1.	ReturnStatement -> node1
2.	node_block_stack_:
	0.	block0
	1.	block1
```

Example trace output:

```
*** SemanticsParseTreeHandler::Build Begin ***
Push 0: FunctionIntroducer
Push 1: DeclaredName
Push 2: ParameterListEnd
Pop 2: ParameterListEnd
Push 2: ParameterList
Pop 2: ParameterList
Pop 0: FunctionIntroducer
AddNode block0: FunctionDeclaration()
AddNode block0: BindName(ident0, node0)
AddNode block0: FunctionDefinition(node0, block1)
Push 0: FunctionDefinitionStart
Push 1: Literal -> IntegerLiteral
AddNode block1: IntegerLiteral(int0): node_xref1
Push 2: StatementEnd
Pop 2: StatementEnd
Pop 1: any (Literal) -> node0
Push 1: ReturnStatement -> ReturnExpression
AddNode block1: ReturnExpression(node0)

    node1 = ReturnExpression(node0);
  },
}

Jon Ross-Perkins 80570e1a5b Modify the driver to support using for semantics IR testing (#2222) 
This unifies `dump-tokens` and `dump-parse-tree` so that we don't keep writing basically the same code repeatedly.

I'll need to modify the output of SemanticsIR::Print more, and may soon unify printing multiple IRs this way (particularly including the builtins SemanticsIR) but this is intended to offer a starting point.

I may eventually try to unify lit.cfg.py files, but I was thinking about whether that works in various contexts we may run in and eventually decided copying the driver/testdata/lit.cfg.py file would be the easiest solution.

Jon Meow 20728dbd3a CARBON_ header guards (#1261) 
This modifies scripts/check_header_guards.py to add the CARBON_ prefix; everything else is pre-commit.

Jon Meow 699172633f Sort diagnostic output from the driver by default (#1143) 2022-03-17 13:27:25 -07:00
Jon MeowandChandler Carruth 652cd8c636 Style updates, mostly _ naming (#970) 
There are some declaration order changes, and a few test classes switched from `struct` to `class`. However, this PR is mostly adopting `_` naming of private member variables due to the shift in naming style. None of what's here should have behavior impacts, it should just be style.

Note, there are a lot of things that *look* like they could be accessor-named, but I'm not doing that in this change. Happy to do it separately if you want me to do another PR focused on it.

Richard Smith d6b47ba10f [toolchain] Add dump-parse-tree command to driver. (#584) 
Also stop producing a redundant additional error message if lexing fails in dump-tokens. The lexer will have produced a diagnostic already.

Chandler Carruth 8f8ab23a77 Move the toolchain into a top-level directory. (#567) 
This should clean up our top level directory and the build patterns.

No non-mechanical edits here. Just injecting `toolchain/` and
`TOOLCHAIN_` and then running formatting tools.
