db2dd20ce6 Parse concurrency syntax when parsing for syntax-tree-only mode. 
This allows the syntax parser library and SwiftSyntax to successfully
parse code using this experimental feature without requiring an API
to pass compiler flags into the parser.

7ee6319cdc [Parse] [Sema] Update confusables diagnostic to mention the character names as well (#33105) 
* [Parser] Update 'Confusables.def' file to include confusable and base character names

* [Parser] Add a new utility method to return the names of the confusable and base characters for a given confusable codepoint

* [Parser] Update diagnostic for confusable character during lexing to mention confusable and base character names

* [Sema] If there is just a single confusable character, emit a tailored diagnostic that also mentions the character names

* [Diagnostics] Add new diagnostic messages to the localization file

* [Test] Update confusables test

* [Utils] Update unicode confusables txt file and update script to regenerate confusables def file

* [Parse] Regenerate 'Confusables.def' using updated script

* [Utils] Adjust generate_confusables script based on review feedback

Fix a mistake with name mapping. Updated header comment. Fix a couple of linting issues.

* [Parse] Regenerate 'Confusables.def' file once again after script changes

* [Parse] Add the newline after end of 'getConfusableAndBaseCodepointNames' method

* [Test] Update diagnostic message in 'Syntax/Parser/diags.swift'

a2fac90284 Revise test for the new multiple-closure syntax. 
This isn't really correct --- we're missing nodes for the call.
But it gets the test passing.

43e2d107e1 [SE-0276] Implement multi-pattern catch clauses 
Like switch cases, a catch clause may now include a comma-
separated list of patterns. The body will be executed if any
one of those patterns is matched.

This patch replaces `CatchStmt` with `CaseStmt` as the children
of `DoCatchStmt` in the AST. This necessitates a number of changes
throughout the compiler, including:
- Parser & libsyntax support for the new syntax and AST structure
- Typechecking of multi-pattern catches, including those which
  contain bindings.
- SILGen support
- Code completion updates
- Profiler updates
- Name lookup changes

0d4cf76ed0 [SyntaxParse] Renew parseListSyntax() 
Optimize for libSyntax parsing.
The new 'parseListSyntax()' receives a vector storage, passes element
builder to the callback for populating the elements, then automatically
parses trailing commas. Also, it performs automatic recovery if the
element has an error (e.g. Skip until ',' or ')').
