Added support for casting with auto declaration

[ryuukk]

That was easy

One step closer to full template support

[WebFreak001]

If you change the code according to my suggestions, also add tests

[WebFreak001]

according to other code in this file typeLookups could be empty. I'm not sure when this would be the case, if you know you could you add a test? Also I would recommend adding a check that aborts or inserts an empty typeLookup

[ryuukk]

it's never empty, it always gets inserted here:

DCD/dsymbol/src/dsymbol/conversion/first.d

Lines 259 to 267 in 1c54fc9

	if (dec.autoDeclaration !is null)
	{
	foreach (part; dec.autoDeclaration.parts)
	{
	SemanticSymbol* symbol = allocateSemanticSymbol(
	part.identifier.text, CompletionKind.variableName,
	symbolFile, part.identifier.index);
	symbol.parent = currentSymbol;
	populateInitializer(symbol, part.initializer);

DCD/dsymbol/src/dsymbol/conversion/first.d

Lines 1085 to 1092 in 1c54fc9

	void populateInitializer(T)(SemanticSymbol* symbol, const T initializer,
	bool appendForeach = false)
	{
	auto lookup = TypeLookupsAllocator.instance.make!TypeLookup(TypeLookupKind.initializer);
	scope visitor = new InitializerVisitor(lookup, appendForeach, this);
	symbol.typeLookups.insert(lookup);
	visitor.visit(initializer);
	}

add a TODO for supporting tip.indexer (D syntax is IdentifierOrTemplateInstance[indexer].typeIdentifierPart)

[WebFreak001]

identifier might not be set (in that case .templateInstance is set)

syntax:
identifier.identifier.templateInstance!(args).identifier

[WebFreak001]

t2 has a member called dot, which means the type starts with a leading dot, e.g. .MyType

This syntax is used to indicate global namespacing, so I think we should add something to the breadcrumbs here to support accessing the global namespace (or if it is global right now, add support to access the local one when it's not dot)

or add a TODO

[ryuukk]

Oh that's a good point, i'll try to add support for that, or if i can't i'll leave a //TODO note
