Geoff RomerandJon Ross-Perkins 74e1a9949f Support tuple patterns outside parameter lists (#4923)
Parameter lists need substantially different treatment than tuple
patterns in other contexts, so this change splits them into separate
parse node kinds.

czapiga 0396bbf9df Improve match parsing diagnostics (#4934)
Adds diagnostics for missing `case` guard parenthesis.
Adds test for which `lex` parenthesis check succeeds but errors are
reported in `parse` phase.

Geoff Romer 943acf1ec2 Separate node kind for bindings inside var (#4822)
This is a step toward making binding pattern handling more robust, by
removing its reliance on the node stack for context.

David BlaikieandJon Ross-Perkins e6c1f0630a Add a newline after diagnostic output when testing (#4818)
This removes some churn when adding new diagnostic cases to test files
(where previous to this change the newly added newline would cause the
previous diagnostic CHECKs to be updated including changes to the line
number because the CHECK for the blank line meant an extra line between
CHECK and source line).

A few alternatives discussed here:

Geoff RomerandJon Ross-Perkins 4f10735751 Track params in the parser (#4777)
This change splits `NodeKind::IdentifierName` into separate node kinds
depending on whether the identifier is followed by parameters, and
similarly splits `NameQualifier` based on whether the qualifier has
parameters. This enables us to only push a pattern block when it's
actually needed, rather than "defensively" pushing one when it might be
needed.

Richard Smith 2e63da1a40 Move diagnostic kind name to the end of the diagnostic. (#4437)
Also surround it in square brackets rather than parentheses. This
matches the format used by Clang and GCC, and means diagnostics will
still match the `file:line:col: error: ` pattern used by some IDE tools.

Before:
```console
fail_builtins.carbon:11:11: error(AliasRequiresNameRef): alias initializer must be a name reference
```

After:
```console
fail_builtins.carbon:11:11: error: alias initializer must be a name reference [AliasRequiresNameRef]
```

Also tighten up test regex to only match on `STDERR` lines that list a
file name.

Jon Ross-Perkins 62c36eceda Support printing the diagnostic kind for verification. (#4425)
This is to help identify which diagnostics we're actually using.

Note that driver/testdata still has tests which don't pass this flag,
and so continue to test the kind-less (default) behavior.

Jon Ross-PerkinsandRichard Smith e7aebbe581 Update basic diagnostic capitalization/punctuation (#4328)
This is a primarily automated change:

- Search & replace for capitalization
-
`(CARBON_DIAGNOSTIC\((?:\n\s+)?\w+,(?:\n\s+)?\s\w+,(?:\n\s+)?\s")([A-Z])`
    - `$1\L$2`
- Search & replace for period
-
`(CARBON_DIAGNOSTIC\((?:\n\s+)?\w+,(?:\n\s+)?\s\w+,(?:\n\s+)?\s"(?:[^)]|\n)+)\.("[,)])`
    - `$1$2`
- Limited search & replace for `ERROR: ` -> `error: ` in streamed things
- Leaving a TODO for command_line because there's more cleanup that can
be done there
- Modify diagnostic_consumer.cpp
    - ERROR -> error
    - WARNING -> warning

Jon Ross-Perkins 1614091da4 Fix match code to consistently diagnose invalid parses. (#4260)
This is a minimal fix to consistently diagnose when producing erroneous
nodes. Leaving a TODO in handle_match

Jon Ross-Perkins 83413479d7 Move some of the test information to TIP lines (#4007)
This has is a nice-to-have for me. Frequently I want to run a specific
test, and end up digging through output to be able to copy-paste the run
line. This uses TIP lines to inject the command into the file when using
AUTOUPDATE.

Note, one of the reasons I want this is because "bazel test
//toolchain/testing:file_test --test_output=all" has been regularly
exceeding bazel's output limit for me (workaround is either opening the
output file or specifying an obscure output limit flag), making it a
little harder for me to get the commands. However, frequently I'm adding
a file and want to iterate on it, so that's really the use case I have
in mind here.

Jon Ross-Perkins b8ceb8dd8b Print a blank line after a diagnostic. (#3806)
The purpose of the newline is to make it clearer where a given
diagnostic begins and ends, particularly as the first message of a
diagnostic may not be the error.

This is a trivial code change, but ripples edits through test files.

Jon Ross-Perkins 03347793cc Switch VariableInitializer order to accommodate GlobalInit (#3708)
This undoes parts of #3515 in order to allow PushGlobalInit to be called
when the initializer is called, instead of at the end of the binding
pattern. The current approach is fragile because supported patterns will
become more complex. We also will likely want similar support in `let`,
which puts the initializer first, so this offers a consistent approach
for both.

[Looking
back](https://discord.com/channels/655572317891461132/655578254970716160/1184237511766179840),
this is more or less the second option in that message, but using the
PeekNextIs to avoid vagueness about what's being popped first.

Note I'm putting in PeekNextIs for what I'm hoping will be a pretty
narrow use-case. I could've added depth arguments to the Peek functions,
but that would've rippled through a number of APIs and it's not clear to
me that this has generic utility. I mean, right now it could just be
PeekNextIsVariableInitializer, since it's only optional in that case.
