Similar treatment as 'SyntaxVisitor'. Reuse `Syntax.Info` when it's safe to do so (i.e. uniquely referenced)
Returnning array literal from computed property allocates and initializes the array buffer every time it's called, and they are deallocated after use. Make them stored properties so they stay in memory.
Building standard operator table is not trivial. Make is an immutable stored property so it stays in memory once it's initialized.
Factor out 'Syntax.Info' reusing into 'SyntaxNodeFactory' and 'SyntaxInfoRepository' as the backing storage. The underlying storage now uses a fixed length 'ManagedBuffer' to avoid 'ContiguousArray' overhead.
Use manually allocated 'UnsafeBufferPointer' to avoid 'ContiguousArray' overhead. Pre-initialize the buffer with the "old" layout at once, and update each element only when updated.
This was a generic function only for casting the result at the end. Hoist the casting part to the caller and make 'visitChilden()' non-generic.
Simpify the iteration code. Also, stop counting 'childIndex' as it can be retrieved from the absolute info.
Use 'SyntaxNodeFactory' in 'SyntaxVisitor' too. Thanks to the simplified implementation, it improves the performance a bit.
Initializer parameters are "+1" in caller site, but these casting initializers only uses the ._syntaxNode and don't store the parameter itself.
- instead of treating as unrecognized, try to parse the remaining tokens as a type even if the preceding colon is missing

… `expansion` method that takes a `conformingTo` parameter The `expansion` method that takes a `conformingTo` has been defaulted to be source-compatible with older versions of swift-syntax that required a version of the `expansion` function without the `conformingTo` parameter. That meant that you could state a conformance to `MemberMacro` without implementing any methods and you wouldn’t get any compile time diagnostics. Deprecate the forwarding default implementation so that you get a warning if you are relying on it.
